A white billiard ball with mass mw = 1.32 kg is moving directly to the right with a speed of v = 2.91 m/s and collides elastically with a black billiard ball with the same mass mb = 1.32 kg that is initially at rest. The two collide elastically and the white ball ends up moving at an angle above the horizontal of w = 20 and the black ball ends up moving at an angle below the horizontal of b = 70.
