Question

A large truck and a small car have a head-on collision. which scenario is true?the truck exerts a greater force on the car than the car exerts on the truck.the car exerts a greater force on the truck than the truck exerts on the car.the force that the truck exerts on the car and the force that the car exerts on the truck are the same magnitude.

Answer 1

A. The truck exerts a greater force on the car than the car exerts on the truck. 

Answer 2

the force that the truck exerts on the car and the force that the car exerts on the truck are the same magnitude.

Step-by-step explanation:

As we know that when truck and car collide with each other then due to this collision the two will exert force on each other

This force will follow Newton's III law

This is law of Action - Reaction as per which force of action must be equal and opposite to the law of reaction.

So we have

`\vec F_a + \vec F_b = 0`

`\vec F_a = -\vec F_b`

so two forces are equal in magnitude but opposite in direction

so correct answer is

the force that the truck exerts on the car and the force that the car exerts on the truck are the same magnitude.
