Suppose a golf ball is hurled at a heavy bowling ball initially at rest and bounces elastically from the bowling ball after the collision

A 2.5-kg ball and a 5.0-kg ball have an elastic collision. Before the collision, the 2.5-kg ball was at rest and the other ball had a speed of 3.5 m/s. What is the kinetic energy of the 2.5-kg ball after the collision?

The figure below shows three identical balls A , B and C. Initially , the baiis B and C are at rest and the ball A while moving with a veiocity v, collides with ball B. if the collision is perfectiy elastic , then after the collision

A super dense ball of very large mass is moving with a certain velocity in a particular direction . This heavy ball collides with a very light ball elastically . Calculate the approximate ratio of velocity of light object after collision to that with velocity of heavy ball .
