Question
A white billiard ball with mass mw = 1.32 kg is moving directly to the right with a speed of v = 2.92 m/s and collides elastically with black billiard ball with the similar 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 horizontal of θw = 22.0° and the black ball ends up moving at an angle below the horizontal of θb = 68.0°.
1) What is final speed of the white ball?
2) What is final speed of the black ball?
3) What is magnitude of the final total momentum of the system?
4) What is final total energy of the system?
