1. The problem statement, all variables and given/known data A billiard ball (ball 1) moving at 5.00 m/s strikes a stationary ball (ball 2) of the same mass. After the collision, Ball 1 moves at a speed of 4.35 m/s. Find the speed of ball 2 after collision 2. Relevant equations Find speed 3. The attempt at a solution The equation im usuing m1v1=m2v2 seems like it might fit??
