Billiardballsnew2 a white billiard ball with mass mw = 1.49 kg is moving directly to the right with a speed of v = 3.09 m/s and collides elastically with a black billiard ball with the same mass mb = 1.49 kg that is initially at rest. the two collide elastically and the white ball ends up moving at an angle above the horizontal of θw = 29° and the black ball ends up moving at an angle below the horizontal of θb = 61°. 1)what is the final speed of the white ball? m/s 2)what is the final speed of the black ball?
