    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??

    After the collision, the balls are moving in the different directions. Resolve the momentums after collision. And solve for the velocity of m2.
