Find their velocities after impact and calculate the loss of KE due to impact if e = 0.5.

A ball of mass 4 kg moving with a velocity of 12 m/s impinges directly on another ball of mass 8 kg moving with velocity of 4 m/s in the same direction. Find their velocities after impact and calculate the loss of KE due to impact if e = 0.5.

A mass m1 moves with a great velocity. It strikes another mass m2 at rest in head-on collision. It comes back along its path with low speed after collision. Then find out whether m1m2.
