A white billiard ball with mass mw = 1.47 kg ismoving directly to the right with a speed of v = 2.97 m/s andcollides elastically with a black billiard ball with the same massmb = 1.47 kg that is initially at rest. The twocollide elastically and the white ball ends up moving at an angleabove the horizontal of θw = 63° and the black ballends up moving at an angle below the horizontal ofθb = 27°.
1) What is the final speed of the whiteball?
1.35 m/s
2) What is the final speed of the blackball?
m/s
3) What is the magnitude of the final totalmomentum of the system?
kg-m/s
4) What is the final total energy of thesystem?
J
