A cue ball of inertia m is given a speed v before it collides elastically with a full rack of 15 stationary balls in a game of pool. Each of the 16 balls has an inertia m.
1) What is the average speed of each ball after they fly apart. Express your answer in terms of some or all of the variables m and v.
2) What is the average momentum of each ball after they fly apart? Express your answer in terms of some or all of the variables m and v.
