On average, the balls are 2.25" in diameter and all balls weigh 5.5 oz. except for the cue, which weighs 6 oz..  The coefficient of restitution for collisions between balls is 0.9.  The cue ball is incident to the two ball so that after collision the two ball go directly towards the one ball. The angle g that the cue ball is incident to the two ball is 20degrees.  If the initial velocity of the cue ball is 1ft/s find the velocity of the two ball after the collision, the velocity of the cue ball after the collision and the carrom angle b.
