Two identical poof balls of 2.37-in-diameter, may move freely on a poof table. Ball В is at rest and ball A has an initial velocity v = υ0i. (a) Knowing that b = 2 in. and e = 0.7, determine the velocity of each ball after impact. (b) Show that if e = 1. the final velocities of the balls form a right angle for all values of b.
