Question

 A heavy truck collides with a car moving at lower speed. After collision the car starts moving at higher speed. This happens in accordance to *


A. Law of Inertia

B. Law of conservation of Mass

C. Law of conservation of Momentum

D. Law of conservation of Angular Momentum

​

Answer 1

Answer:

C.

Explanation:

By the law of conservation of momentum, "For a collision occurring between object 1 and object 2 in an isolated system, the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision."

After the collision, the velocity of the car increases as its momentum increases.
