Momentum and CollisionHard
Question
A body moving towards a body of finite mass at rest, collides with It is impossible that
Options
A.both bodies come to rest
B.both bodies move after collision
C.the moving body stops and body at rest starts moving
D.the stationary body remains and the moving body rebunds
Solution
For (A) : Momentum can′t destroyed internal forces.
For (D) : If mass of stationary body infinite then the moving body redounds.
For (D) : If mass of stationary body infinite then the moving body redounds.
