Question

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

• A. both the bodies come to rest
• B. both the bodies move after collision
• C. the moving body comes to rest and stationary body starts moving
• D. the stationary body remain stationary and moving body changes its direction

Answer 1

Answer: (B), (C)

The correct options are
B the moving body comes to rest and stationary body starts moving
C both the bodies move after collision

If a body moving towards a finite body at rest collides with it then momentum will be conserved and hence, the velocities after collision are may be in inverse proportion to their masses or may get interchanged. Hence, both the bodies move after collision or the moving body comes to rest and stationary body starts moving.
