# a compact car and a semi truck are both traveling

## Why do two vehicles experience the same force in a collision?

The two vehicles experience a force of the same magnitude due to Newton’s third law: However, what you’re probably thinking about is that motion of the car is more drastically affected by the collision. This can be explained by Newton’s second law. Let’s say the truck has mass M and the car has mass m.

## Are the forces on a truck and a car the same?

The forces on the car and truck are equal and opposite. However, the force on someone sitting in either vehicle is not the same (assuming the frame around them stays rigid enough). As joshphysics explained, the equal forces cause accellerations of the truck and car inversely proportional to their mass.

## What happens to momentum when a truck and a car collide?

During the small time frame of the collision we generally assume that there is no transfer of momentum into or out of the system of the car and truck. Changes of momentum are called impulses and are calculated by The duration of the collision is Δ t so the force of the car on the truck lasts exactly as long as the force of the truck on the car.

## Why does a truck accelerate faster than a car in collision?

However, what you’re probably thinking about is that motion of the car is more drastically affected by the collision. This can be explained by Newton’s second law. Let’s say the truck has mass M and the car has mass m. If the magnitude of the force that both vehicles experience is F, then the magnitudes of their respective accelerations are

## How many Q&A communities are there on Stack Exchange?

## Is the force on a car and truck the same?

The forces on the car and truck are equal and opposite. However, the force on someone sitting in either vehicle is not the same (assuming the frame around them stays rigid enough). As joshphysics explained, the equal forces cause accellerations of the truck and car inversely proportional to their mass. Assuming you sitting in one of these vehicles are a relatively small portion its overall mass, then what you feel is proportional to the accelleration of the vehicle around you.

## Is it better to sit in a car or drive in a collision?

Even putting aside getting physically crushed, you are therefore better off in a more massive vehicle in a collision. Think of a extreme case. You are driving a long and a bug gets splatted on the windshield. Your car and the bug both got pushed with the same force, but the resulting change in velocity (the accelleration) of the bug was much higher. As a result, you sitting in the car had a rather better experience than the bug.

## How many compartments are there in a train?

## How fast does a 910 kg car go?

A 910 kg sports car slows down to** 6.0 m/s ** to read a cross street sign. The 1440 kg pick-up truck following the sports car fails to see that the sports car has slowed and continues traveling at 17.0 m/s. The pick-up slams into the sports car. With what

## What is a semi trailer?

## What is the speed of a car in an easterly collision?

A 1,225-kg car traveling initially with a speed of** 25.0 m/s ** in an easterly direction crashes into the rear end of a 8,500-kg truck moving in the same direction at 20.0 m/s. The velocity of the car right after the collision is 18.0 m/s to the east. (a) What

## How far away is a car traveling 100 km/h?

A car traveling 100 km/h is** 200m ** away from a truck traveling 50 km/h (in the same direction). Assuming constant braking acceleration, what is the minimum deceleration the car must have if it is not to hit the truck? Can someone hint me on how I can start
