Two identical small cars (car A & car B) have a head-on collision. Which scenario is true?

ACar A exerts a greater force on car B than car B exerts on car A.
BCar B exerts a greater force on car A than car A exerts on car B.
CThe force that car A exerts on car B and the force that car B exerts on car A are the same magnitude.

Verified Answer :

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

Answer:

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).
