Here we are given that  

 
Thus after collision, the two balls bounce back with equal speeds.

A 0.15kg glider is moving to the right on a frictionless horizontal air track with a speed of 0.80m/s .It has a head on collision with a 0.300 kg glider that is moving to the left with a speed of 2.2m/s .Find the final velocity (magnitude and direction) of each glider if the collision is elastic.

prove that in an elastic one dimensional collision between two bodies, the relative velocity of approach before collision is equal to the relative velocity of seperation after the collision. Hence derive expressions for the velocities of two bodies in terms of their initial velocities before collision.
