Collision problem.. Physics help?

In a game of billiards, the cue ball has a mass of 0.26 kg, and each numbered ball has a mass of 0.15 kg. The cue ball is moving with a speed of 2.2 m/s when it strikes the 8 ball, which is initially at rest. After the collision, the cue ball goes off at angle=18 degrees relative to its original direction, and the 8 ball moves off at angle 2= 35 degrees. Hint angle 2 is a negative angle

A) what is the initial momentum of the two ball system?
0.572 kg/msec

B) what is the final speed of the cue ball?

C) what is the final speed of the 8 ball?

D) how much kinetic energy is lost in the collision?

Thanks!
