A body of mass m moving with velocity vecV collides elastically with another body B of same mass which is at rest. What will be the velocities of A and B after collision?

A body of mass m, moving with velocity mu collides elasticity with another body at rest having mass M. If the body of mass M moves with velocity V, then the velocity of the body of mass m after the impact is
