Calculating Collision Speeds: Billiard Ball Physics Homework Solution

[eddwinn]

Homework Statement

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

Homework Equations

Find speed

The Attempt at a Solution

The equation I am usuing m1v1=m2v2 seems like it might fit??
