Elastic collisions

Perfectly elastic collisions:
An elastic collision is one in which momentum and kinetic energy are conserved during the collision. 

elastic collisions

Two identical objects A and B, moving at the same speed but in opposite direction, have a head on collision, just as shown in figure 1. This is a perfectly elastic collision. Each object bounces back with its velocity reversed. In this collision both momentum and kinetic energy are conserved.
The total kinetic energy of object A and object B before the collision can be found by using the formula mv2

Which is derived from

1/2mv2+1/2mv2 = mv2
