A stationary billiard ball, mass 0.17 kg, is struck by an identical ball moving at 3.0 m/s. After the collision, the second ball moves off at 60° to the left of its original direction. The stationary ball moves off at 30° to the right of the moving ball's original direction. What is the speed of each ball after the collision?
final speed of initially stationary ball ?
final speed of initially moving ball ?
