Question

A body of mass m 1 moving at a constant speed undergoes an elastic head-on collision with a body of mass m 2 initially at rest. The ratio of the kinetic energy of mass m 1 after the collision to that before the collision is, m 1 - m 2 m 1 + m 2 2, m 1 + m 2 m 1 - m 2 2, 2 m 1 m 1 + m 2 2, 2 m 2 m 1 + m 2 2

m 1 v 0 = m 2 v 2 - m 1 v 1 .........(1) e = v 1 + v 2 v 0 = 1 .........(2) Solving (1) and (2) v 1 v 0 2 = m 1 - m 2 m 1 + m 2 2
