One of the best tools I've found for the calculations.

Going 65mph for 30 seconds how far would you get? None of these formulas work without distance. How would I find the distance from time and speed?

if i travel 0.01 inches per second and I need to travel 999999999 kilometers, it takes 556722071 Days and 20:24:34 WHAT

4. How long does it take to do 100m at 3kph ? No I thought you would just divide 100 ÷ 3 = which 33.33333 so 33 seconds or so I thought. But apparently it 2 mins.

This was the best tool ive ever used that was on point from speed to distance and time Calculator

This was somewhat unhelpful as I know the time and distance, but not the speed. Would be helpful if this calculator also could solve the other two as well.

If a total distance of 2 miles is driven, with the first mile being driven at a speed of 15mph, and the second mile driven at a speed of 45 mph: What is the average speed of the full 2 mile trip?

hi sorry im newly introduced to this and i dont understand how to use it but in need to find the distance if i was travelling in the average speed of 15km/hr in 4 hours how far would i travel

D= 697 km T= 8 hours and 12 minutes S= ?

if a train is going 130 miles in 50 minutes, how fast is it going in miles per hour ??

whats the speed if you travel 2000 miles in 20hours?

How long would it take me to drive to Mars at 100 miles per hour and how much gas would I use in a 2000 Ford Mustang000000/ Also, how much CO2 would I release into the air?

great tool helped me alot

A car can go from rest to 45 km/hr in 5 seconds. What is its acceleration?

Guys how much time will a cyclist take to cover 132 METRES With a speed of 8 km/ph

@Mike Depends on how fast that actually is. For every 10 mph above 60, but below 120, you save 5 seconds a mile. But between the 30-60 area, every ten saves 10 seconds a mile (if I am remembering correctly), and every 10 between 15-30 is 20 seconds. Realistically, it isn't likely isn't worth it, unless it is a relatively straight drive with no stops, in which case you will likely go up a gear for the drive and thus improve gas efficiency for the trip. Only really saves time if it is over long trips 300+ miles (in which case, assuming you were on the interstate) that 5 seconds a mile would save you 25 minutes from the drive, making it go from 4h35m to 4h10m. For me, I have family across the U.S., so family visits are usually 900-1400 miles. Even only driving 5 above usually saves me 90-150 minutes or so (since I often have stretches where I drive on US highways which have 55 mph speed limits)

I would like to know if driving fast is worth it for short trips. If I drive 10 MPH over the speed limit for 10 miles, how much time do i save ? Is there an equation for that ?

it helps me in lot of stuff

awesome, helped me notice how long my taiga (electric seedoo) is going to last.

Keep Your (Braking) Distance: More Than Just Slowing Down

Although we at Edmunds.com spend a lot of time writing about rpm, torque, 0-to-60-mph acceleration, etc., nothing is more important than your car's ability to stop itself. Knowing something about braking distances (how much ground a vehicle covers before it can fully stop) can make for safer and more enjoyable driving.

Let's start with the basics. A vehicle traveling at 60 mph covers 88 feet per second. But stopping that vehicle takes over 4.5 seconds and covers a distance of 271 feet. Why? Because there's more involved in braking than the actual time your brakes are applied to the wheels (called "effective braking"). In particular, "perception time" and "reaction time" add considerable distance to stopping your car.

Perception time is the three-quarters of a second it takes for you to realize that you need to brake. Reaction time is the three-quarters of a second it takes to move your foot to the brake pedal. When you combine perception and reaction time, a full 132 feet will pass before your car even begins to slow down from 60 mph. So from the time you perceive a braking situation until the time your car comes to a complete stop, a total of 4.6 seconds elapses. During that time your car travels — it bears repeating — a total of more than 270 feet. That's almost the length of a football field. Of course, the faster you go, the more time and distance it takes to stop.

See Edmunds pricing data

Has Your Car's Value Changed?

Used car values are constantly changing. Edmunds lets you track your vehicle's value over time so you can decide when to sell or trade in.

There are other factors as well, such as road conditions. When weather is bad, your braking distance grows exponentially. On wet pavement, total braking time increases from 4.6 seconds to 6.1 seconds, and total braking distance shoots up from 271 feet to 333 feet. And it gets worse. In snowy conditions, even with snow tires, total stopping time jumps to 10.6 seconds and 533 feet. As a basis of comparison, this is roughly the same distance — actually, a little further — as the same vehicle coming to a complete stop from 90 mph on dry pavement, an effective doubling of the braking distance. Let us repeat that: a 100-percent increase .

So what do we do with all these numbers? There's nothing we can do about the weather or about road surfaces, but we can do something about the way we drive. Arming ourselves with knowledge can prevent the loss of property and human life.

First, if you drive a truck or SUV, be especially cognizant of your speed in bad weather. Sitting higher off the road than everyone else only means you'll have a better view of the passing countryside as you slam sideways into a snowbank.

Second, remember this law: That which makes you go won't make you stop. If you drive a four-wheeler, you're not immune to the laws of physics, in fact you're a bit more susceptible (if for no other reason than your overconfidence). Whether you drive an Escort or an Excursion, it doesn't matter. In fact, the heavier weight of a truck or SUV means it will take much longer to come to a stop, given its greater momentum. Repeat: four-wheel drive does not help you stop . We're tired of seeing you folks spun around on the side of the road facing the wrong way. Slow down before you hurt somebody.

Third, remember to keep a "space cushion" around your vehicle at all times — ahead, to the sides and behind your car. This can be difficult to accomplish, especially in heavy traffic where everyone is darting in and out. How close is too close when it comes to following the car ahead of you? There's a handy "3-second rule." When the vehicle ahead of you passes a certain point, such as a sign, count "one-thousand-one, one-thousand-two, one-thousand-three." This takes about 3 seconds. If you pass that certain point before you finish counting, you are following too closely. We suggest a 4-second (or more) cushion in inclement weather.

Fourth, the tires you choose and their condition are another important, yet often overlooked, factor. See our articles, " Tire Safety: Don't Ignore the Rubber on the Road " and " Tires: Traffic Safety Tips " for all the details on tire selection and maintenance.

There are a few other factors that affect braking distances. As stated before, the heavier your vehicle is, the longer it will take to stop. Bear that in mind when you shop for a car or when you load it up. Also, the looser the road surface (gravel, dirt, mud), the harder it is to stop.

Finally, we strongly recommend that buyers choose a car equipped with antilock brakes (ABS), which, with few exceptions, help decrease braking distances on any road surface and in any weather. Whenever a driver slams on the brakes (and it's happened to everyone), the tires have the potential to lock up, sending you skidding. In a skid, tires have little traction, you lose steering control and braking distance is greatly increased. Antilock braking systems are designed to prevent tire lockup by automatically and rapidly "pumping" the brakes, potentially decreasing braking distances in extreme situations.

Of course, in order to get the most out of ABS in emergency braking situations, you have to know how to use it. And really, it couldn't be easier; you just stomp on the pedal. Some drivers are inclined to ease up on the brake pedal when they feel the vibration (and hear the noise) of the ABS doing its work, but it's important to maintain constant, controlled pressure. Aware that people often don't supply enough braking pressure, many manufacturers now supplement their antilock systems with "brake assist," which senses panic braking situations and automatically provides full power braking to shorten the stopping distance.

Many new cars come with antilock brakes as standard equipment, but you must often purchase them as an option on low- to moderately priced cars. And on some models, you may have to step up to a higher trim level to get ABS. Regardless, antilock brakes are a worthwhile feature and we highly recommend that you spend the extra money to get them.

What about disc brakes? Do they make a difference? Today we usually find four-wheel-disc brakes as standard equipment on most midpriced coupes, sedans, wagons and SUVs. Many economy vehicles and pickup trucks, however, continue to utilize a front-disc/rear-drum brake setup, which in most cases provides adequate performance for the general consumer. Nevertheless, vehicles with four-wheel discs usually deliver shorter stopping distances and are less susceptible to fade (loss of braking performance due to heat).

Whether you're reacting to sudden slowdowns on the highway or to a child darting into the street, nothing is more important than safe, well-maintained brakes (and the tires that work with them). Have them inspected according to the maintenance schedule in the owner's manual, and don't wait to have them checked out if you notice a pedal vibration or excessive noise when braking. That squeal you hear is probably telling you something — something that would be cheaper to fix now rather than later.

Additionally, being aware of all the variables — your proximity to other vehicles, weather conditions, road surface — will help you judge proper speed and give you time to react to whatever comes your way.

US Standard Speed (Velocity)

These are the most common measurements:

  • Feet per Second (fps)
  • Miles per Hour (mph)


Speed in feet per second (fps)

If something is traveling at 1 fps it moves 1 foot every second .

It is a very slow walking pace.

An hour and a half at 1 fps moves you about 1 mile.

Speed in miles per hour (mph)

If something is traveling at 1 mph it moves 1 mile every hour .

It is a slow walking pace.

One hour walking at 1 mph moves you 1 mile.

Miles per hour is often used for car speeds.

car and dust

Example: Highway speed is around 60 mph

One hour at 60 mph will move you 60 miles

One minute at 60 mph will move you 1 mile

You can convert from fps to mph:

  • 1 mph = 1.4666... fps
  • 1 fps = 0.68181818... mph

Example: What is 60 mph in fps?

A mile has 5,280 feet, and an hour has 3,600 seconds, so 60 miles per hour is:

  • 60 x 5,280 / 3,600 = 88 fps

60 mph = 88 fps

Velocity is speed with a direction .

So if something is moving at 5 mph that is a speed .

But if you say it is moving at 5 mph westwards that is a velocity .

If something moves backwards and forwards very fast it has a high speed, but a low (or zero) velocity.

More Examples

3 mph (miles per hour) is about:

  • typical walking speed of a human or dog

35 mph is about:

  • the speed limit in the city
  • going very fast on a bicycle
  • the speed of a racehorse on a short track
  • full running speed of a Bengal Tiger

60 mph is about:

  • how fast you can legally go on a highway
  • the maximum running speed of a cheetah
  • the speed needed to drive one mile in a minute
  • half the freefall speed of a skydiver

1 fps (foot per second) is:

  • exactly 0.3048 meters per second
  • approximately 0.6818 miles per hour
  • exactly 1.09728 km per hour

Car Crash Calculator

Table of contents

Our car crash calculator is a tool that you can use to estimate what g-force acts on you in a car crash. Everybody knows that automobile collisions are very dangerous, but what is the physics behind them? Can we predict the consequences of a car crash? The answer is yes and no. The damages to health in an accident can be severe, and they depend on many factors, e.g.:

  • Car speed – the higher the speed, the more energy you have;
  • Seat belt – we will show that seat belts can save your life;
  • Airbag – another thing that can protect your life;
  • Car type – you are more likely to survive a car crash if you're in a bigger car; and
  • Obstacle – the situation is different when we hit a bush or a tree.

We can't precisely calculate whether you will survive or not, but we can make some estimations to be aware of crash consequences. What happens if you drive at a speed of 20   m p h 20\ \mathrm{mph} 20   mph and you suddenly stop? Just imagine that a 7-tonne block lies on your chest . Yes, it's almost the same. Recently, the NHTSA (National Highway Traffic Safety Administration) performed many crash tests with dummies. Based on these tests, we can make some approximations at what speed you can die in a car crash.

In this car crash calculator, we explain how to calculate the impact force in car crashes and how seat belts and airbags can protect you. You'll find out that they can drastically increase your chances of surviving. You can learn about the force of impact definition and impact force equation in the following text.

You do not need to be the driver to know that you can't stop the car immediately . The total stopping distance depends on the perception time of a driver and the braking distance. The same energy estimated with the kinetic energy calculator will be dispersed much faster on a tree than in water. Thus, hitting trees almost always results in dangerous car crashes.

Force of impact definition – impact force equation

Force of impact is the total force exerted on an object during a collision. To derive the impact force equation, you can consider the law of conservation of energy. In the beginning, a moving object possesses kinetic energy that reduces to zero after the collision (object stops). To fulfill the conservation law, the change of kinetic energy must be compensated by the work done by the impact force. We express it with the below impact force equation

  • F F F – Average impact force;
  • m m m – Mass of an object;
  • v v v – Initial speed of an object; and
  • d d d – Distance traveled during a collision.

Check the work calculator or work and power calculator to get familiar with work in physics and how it is related to energy.

What may surprise you is that extending the distance moved during the collision reduces the average impact force. It should be easier to understand if we rewrite the above impact force formula in the alternative version using the time of collision t t t instead of the distance d d d :

This is a special case of the formula for momentum, described in the impulse and momentum calculator . Now, you can see that extending the time of the collision will decrease the average impact force.

Let's consider two situations where you jump from a specific height. In the first case, you jump to the ground, and in the second, on a trampoline. Because the surface of a trampoline is more stretchy, it extends the time of the collision. You can feel your legs are subjected to a lesser average impact force.

This case is analogical to car crashes. Cars are made to collapse upon impact extending the time of the collision and lessening the impact force. That's why they can't be too durable.

How to calculate impact force? G-force in car crashes

The impact force formulas we used above describe an ideal collision between two objects. In the actual situation of a car crash, the profile of force during the accident can be more extensive – e.g., you should take into account that the car collapses and that a human is not a point mass but a complex body. However, you can still make some estimations of impact force during a car crash.

Take a look at the picture below. At first, the driver sits in the car in constant motion with speed v v v . Then, a car hits the tree and immediately stops. The driver flies forward due to the inertial force until suddenly stopped by the impact on the steering column or windshield. The stopping distance is very short because none of the colliding objects (including the body and, e.g., the windshield) are contractible enough. These are usually dense objects; you can find the density of the most common materials with the density calculator for a comparison. We can estimate the stopping distance to be approximately 4   c m 4\ \mathrm{cm} 4   cm in our case (you can change it in the "Additional variables" section of this impact force calculator).

Stopping distance without seat belts.

How to calculate the impact force acting on a driver with a mass of 70   k g 70\ \mathrm{kg} 70   kg ? Let's use our car crash calculator! If the initial car speed is 30   k m / h 30\ \mathrm{km/h} 30   km/h and the collision distance is 4   c m 4\ \mathrm{cm} 4   cm , then the impact force is about 60   k N 60\ \mathrm{kN} 60   kN . It is an equivalence of 6 tons! It is just as if someone put a large stone block on your chest. On the other hand, the stopping time is only 9.6   m s 9.6\ \mathrm{ms} 9.6   ms which means that to reduce the driver's velocity from 30   k m / h 30\ \mathrm{km/h} 30   km/h to zero, the driver has to decelerate almost 89 times faster than Earth's standard gravity g .

How can seat belts and airbags protect you?

The primary task of seat belts and airbags is the same. They both extend the distance of the collision . Assume that we've got the same situation as before. The 70   k g 70\ \mathrm{kg} 70   kg driver drives a car with a speed of 30 km/h, but this time, he is firmly held in a seat belt harness. The seat belt will stretch slightly when the impact force is applied. We can say that it can expand by about 20   c m 20\ \mathrm{cm} 20   cm (you can change it in the "Additional variables" section of this impact force calculator).

Stopping distance with seat belts.

Again, after using the car crash calculator, you can obtain the average impact force of about 2.5   k N 2.5\ \mathrm{kN} 2.5   kN , which is almost 25 times smaller than without the seat belt. It corresponds to a weight of 1.24   t 1.24\ \mathrm{t} 1.24   t . The stopping time lengthens to 48   m s 48\ \mathrm{ms} 48   ms , and now, the driver decelerates "only" 18 times faster than with Earth's standard gravity g.

To sum up, the seat belt is designed to stop your body from hitting hard things in the car and reduce the impact force you experience by spreading it out over time . The seat belt could occasionally contribute to severe internal injury or even death if the impact force is too big. However, nowadays, seat belts have a mechanism that breaks them at a predefined level of stress. Usually, there are still airbags placed in front of the driver in order to increase their safety.

We have made an example with the driver, but any person in the vehicle is subjected to these dangers. If you crash with a heavy truck, it doesn't matter whether you sit behind the wheel or at the back seat of the car.

Even in low-speed collisions, the impact force which stops your body is in the range of tonnes . You simply won't be able to hold on and prevent injury without fastened seat belts. Moreover, if you sit at the back of the car and you aren't constrained by a seat belt, you will fly straight ahead like a boulder of several tonnes. You will not only hurt yourself but also your friend in front of you!

At what speed can you die in a car crash?

This is one of those questions that doesn't have one unambiguous answer . The heavier the car is, the harder it is to stop it, and the impact force is smaller. On the other hand, the vehicle will immediately stop if it hits a wall of a house, but the situation will be different if it hits another car that participates in traffic. Therefore, we must take into account many different factors.

In general, high speed doesn't produce harmful injuries . What is dangerous for a human is the high acceleration or deceleration given at a specific amount of time. The National Highway Traffic Safety Administration (NHTSA) is an agency that conducts traffic safety research around the world. It describes its mission as Save lives, prevent injuries, reduce vehicle-related crashes . The NHTSA states that "the maximum chest acceleration shall not exceed 60 g for time periods longer than 3 milliseconds " (source: NHTSA ).

With our car crash calculator, you have learned that the accelerations during car crashes can be a lot higher than 60 g without fastened seat belts. So use them and save your life! NHTSA states that seat belts reduce death rates by 45% and reduce the risk of injury by 50%.

How do I calculate the forces in a car crash?

To calculate the impact force in a car crash, follow these simple steps:

  • Measure the velocity at the moment of the impact, v .
  • Measure the mass of the subject of the collision, m .
  • The stopping distance d in the formula: F = mv²/2d ; or
  • The stopping time t in: F = mv/t
  • If you want to measure the g-forces, divide the result by mg , where g = 9.81 m/s² .

What is the impact force in a crash at 160 km/h?

Assuming the weight of the driver is 70 kg , we can calculate the impact forces in two situations:

  • Without the seatbelt, the stopping distance would be 4 cm , and the impact force is: F = 70 kg × (44.44 m/s)²/(2 × 0.04 m) = 1728 kN
  • With the seatbelt on, the stopping distance increases to 20 cm . The force becomes: F = 70 kg × (44.44 m/s)²/(2 × 0.2 m) = 346 kN

Divide F by m × g = 686.7 m/s² to find the deceleration in terms of g . It’s 2517 g without a seatbelt and 504 g with.

Why does wearing a seatbelt increase your safety?

A seatbelt extends the time your body slows down from the speed before the crash to 0. In a car crash, speed is not the only factor that can be dangerous: the stopping time and distance have an even more critical role. A seatbelt keeps you in your seat, only partially expanding, thus distributing the deceleration over a safer time. However, they are not a guarantee: drive safely, always!

How do I find the stopping time in a car crash?

We can find the stopping time from the impact force using the following formula: t = m × v/F where:

  • t — The stopping time ;
  • m — The weight of the victim ;
  • v — The speed of the vehicle; and
  • F — The impact force .

You can find the stopping distance with the simple relationship between time and space: d = t × v/2

Impact Force Calculator

Calculate an approximate average impact force and peak impact force from a collision of a moving body with output in Newtons (N, kN, MN, GN) and pound-force (lbf). The impact force calculator is versatile and can also be used to calculate the mass, velocity and either collision distance or duration. Works as a car crash force calculator, falling object impact calculator, etc.

    Using the impact force calculator

This versatile impact force calculator is useful for estimating the impact forces involved in collisions of different kinds. For example, it can be used to calculate the impact force of a vehicle (car, truck, train), plane, football, of birds hitting a plane or wind mill, as well as for falling bodies that crash into the ground. It can also be used to calculate the force of impact of different kinds of projectiles. You need to know the body's mass, velocity on impact (can be calculated if you know its acceleration and the duration of its travel time) and either collision duration (from first contact to the end of the collision process) or collision distance, e.g. the depth of the bent on a car bumper following a crash.

The impact force calculator can also be used to solve for any of the other values: mass, velocity, impact duration and deformation distance . The respective input fields will be hidden or displayed upon selecting what you want to use the calculator for.

The output if calculating collision force is in Newtons or KN, MN and GN, as well as pound-force (lbf). For other outputs it is in both standard metric units and imperial ones, with the units automatically being adjusted depending on how big or small the resulting value is.

    Impact force formula

The formula for impact force expressed in terms of the body's velocity (speed) on impact ( v ), its mass ( m ), and the collision distance ( d ) is the first formula below:

impact force

whereas the second equation is applicable if instead of the collision distance we know the duration of the collision ( t ) which is Δt = t 1 - t 0 where t 0 is the first moment in which the bodies connect and t 1 is the moment they reach the end of the deformation process by either denting or bouncing off each other. This formula will output the result in Newtons, assuming your input was in the correct standardized metric units: kilograms, meters, seconds, meters per second. Straightforward transformations of these impact force formulas lead to calculations for the body mass, velocity on impact, collision distance or collision duration, all supported by our force calculator.

The above equation can be used to calculate both impact force of a falling ojbect as well as impact force of a horizontally-moving object such as in a car crash or plane crash . The formula can easily be extended to calculate the approximate maximum impact force (a.k.a. peak impact force) by multiplying the resulting average impact force by two.

If one thinks about force on impact in terms of development of safety measures and equipment, then it is immediately obvious that since the body mass is usually constant, the variables one can alter are the speed (hence speed limit laws on most roads) and the collision distance or collision duration, which are usually two sides of the same coin. Car manufacturers, for example, make cars less sturdy than they can be so they can crumble when excessive force is applied to them, thus increasing the deformation distance and hence the impact duration, which results in lower impact force during a car crash.

    Formula accuracy

The impact formula has decent accuracy, but just as any physical model is just an approximation. Certain assumptions regarding spring force and wave propagation, as well as the hardness of the materials involved will hold differently in different situations. Results from this impact force calculator should mostly be used as a teaching device and a rough guideline, however some demonstrate [3] that the equations can be used to determine the appropriate force sensor measuring range during impact testing, stating that the "perfect rebound assumption" which is part of the formula performs well at least in the case discussed in the white paper.

    Calculation examples

Example 1: Car crash force. A car weighs 2400kg (2.4 tonnes) and is moving with a constant speed of 27 km/h when it hits a light pole head on. The deformation distance is measured at 75cm. What is the impact force of the car?

First, we need to convert km/h to m/s, which gives us 27 / 3.6 = 7.5 m/s. Then we apply the first equation since we know the deformation distance, which is 75 cm = 0.75 meters. Replacing in the formula we get F avg = 0.5 · 2400 · 7.5 2 / 0.75 = 90 kN and a maximum impact force of 180 kN. ( calculation link )

Example 2: Using the situation in example 1, but now instead of knowing the depth of the dent, we were lucky enough for the impact to be caught on a high-speed camera and we can measure that it took 0.2 seconds from start to end. The average impact force is then simply 2400 · 7.5 / 0.2 = 90 kN. Thus, we can see it was the same incident described in different measures. Just out of curiosity we can increase the car's velocity to 54 km/h (15 m/s) while keeping everything else the same and we now get twice the force: 180 kN and a peak at 320 kN. For this to happen our car would need to deform a whopping 150 cm (1.5 meters) in 0.2 s.

Example 3: Calculating the impact force of a falling object , without taking into account air friction. Let's say there is a 250 kg piano hanging 5 stories high or about 15.5 meters and we drop it on hard concrete. What is the impact force, if we measure that the collision pulse is about 0.2 seconds?

First, we need to use the acceleration and distance to calculate the velocity on impact. g is 9.80665 m/s 2 and the distance 15.5 meters so the speed so we get the velocity on impact to be v = √(2 · a · d) = √(2 · 9.80665 · 15.5) = √304 = 17.44 m/s (a nice 1.8 s fall). We subsitute in the second formula above and get F avg = 250 · 17.44 / 0.2 = 21.8 kN and F max = 43.6 kN of impact force acting on the object. check the calculation

Ton vs tonne, tons vs tonnes

When calculating the body mass, we output both tonne (metric ton) and ton (short ton). The first one is used by all countries in the world and is defined to be equal to 1000 kg by the international body of standardization. The ton is currently only used in the United States and is equal to 2000 pounds (2000 lbs).

Postal worker caught racing Mustang in USPS van, hitting 105 mph

FREMONT, Ohio ( WTVG /Gray News) - Body camera video shows a traffic stop in Ohio where a deputy had just pulled over a United States Postal Service mail van for speeding at more than 100 mph in a 60 mph zone.

“Is there a reason you’re going over 100?” a Sandusky County deputy asked in the video.

The driver replied, “I didn’t realize I was going that fast.”

The stop happened just before 2 p.m. on April 21 on Route 20 just west of Fremont.

According to the traffic report, the van had no plates and the driver appeared to be racing a Ford Mustang.

In the body camera video, the deputy goes on to say, “Yeah. I mean, that Mustang took off. He caught my attention, and then you blew by him, and I was pacing you at like 105.”

Court records identified the driver as Drew Brown, 28. She told officials she worked for the Fremont post office.

Brown waived the case, which is now closed, and paid a $50 fine for the traffic violation after receiving a verbal warning for racing.

A spokesperson for the USPS shared the following statement:

“Drew Brown is an employee. It is under investigation and as a matter of policy, we are unable to comment further on a specific individual personnel matter.”

  20. PDF Vehicle Stopping Distance

    You may want to use our Vehicle Stopping Distance Calculator to do actual model calculations. 60 MPH = 88 fps. (fps=1.467 * MPH). If the vehicle deceleration rate is 20 fpsps (rather than the previously calculated 15 fps), then stopping time = 88/20 = 4.4 seconds. Since there is a 1 second delay (driver reaction time) in hitting your brakes ...

  21. Impact Force Calculator

    First, we need to convert km/h to m/s, which gives us 27 / 3.6 = 7.5 m/s. Then we apply the first equation since we know the deformation distance, which is 75 cm = 0.75 meters. Replacing in the formula we get F avg = 0.5 · 2400 · 7.5 2 / 0.75 = 90 kN and a maximum impact force of 180 kN. ( calculation link)
