When a massive body suffers an elastic collision with a stationary light body, then massive body approximately comes to rest and light body

when a body is stationary:

A body of mass m having an initial velocity v , makes head on collision with a stationary body of mass M . After the collision, the body of mass m comes to rest and only the body having mass M moves. This will happen only when

When a body is stationary

Consider the following statements A and B and identify the correct answer A. In an elastic collision, if a body suffers a head on collision with another of same mass at rest, the first body comes to rest while the other starts moving with the velocity of the first one B. Two bodies of equal mass suffering a head on elastic collision merely exchanges their velocities
