## Homework Statement

A ball of mass 5.0kg moving at a speed of 5.0m/s has a head on collision with a stationary bal of mass 6.0kg. If the collision were perfectly elastic what would be the speeds of the two balls after the collision?

## Homework Equations

P = mv

KE = 0.5mv

^{2}

## The Attempt at a Solution

Using together kinetic energy and momentum equations, I can solve for final velocities.
