A body is moving towards a finite body which is initially at rest, and collides with it. In the absence of any external impulsive force, it is possible that
The moving body comes to rest and the stationary body starts moving
The correct options are (b) and (c)
Step 1: Momentum conservation
When a moving body collides with a stationary finite body, momentum is preserved, and the velocities after the impact may be in inverse proportion to their masses or may be interchanged.
Step 2:
As a result, both bodies move following a collision, or the moving body comes to a halt and the stationary body begins to move.
If both bodies come to rest, then momentum will not be conserved. So, option (a) is incorrect.
Hence, the correct options are (b) and (c)
