Two identical small cars (car a & car b) have a head-on collision. which scenario is true?

a. car a exerts a greater force on car b than car b exerts on car a.
b. car b exerts a greater force on car a than car a exerts on car b.
c. the force that car a exerts on car b and the force that car b exerts on car a are the same magnitude.

The force that car A exerts on car B and the force that car B exerts on car A are the same magnitude.

Explanation:

There can be two types of collision i.e. elastic and inelastic collision. Elastic collision is also known as head-on collision. In this type of collision, the momentum and kinetic energy before and after the collision remains the same.

If two identical small cars (car A & car B) have a head-on collision, then the force that car A exerts on car B and the force that car B exerts on car A are the same magnitude. It is due to Newton's third law of motion which states that there is an equal and opposite reaction when one object applies a force on another object. So, the correct option is (c).
