A body moving towards a finite body at rest collides with it. It is possible that

Options

A. both the bodies move after collision
B. both the bodies come to rest
C. the stationary body remains stationary, the moving body changes its velocity
D. the moving body comes to rest and the stationary body stationary body starts moving.

Answer

A, D

Explanation

When a body collides with a finite body at rest, both the bodies cannot come to rest. Neither the stationary body can remain stationary as momentum of the two bodies is shared and conserved. Choice `(a)` and `(d)` are correct.
