Chapter 14.1, Problem 14.23P
In a game of pool, ball A is moving with a velocity v0 = (10 ft/s)i when it strikes balls B and C, which are at rest side by side as shown. After the collision, A is observed to move with the velocity vA = (3.92 ft/s)i − (4.56 ft/s)j, while B and C move in the directions shown. Determine the magnitudes of the velocities of B and C.

An expert archer demonstrates his ability by hitting tennis balls thrown by an assistant. A 2-oz tennis ball has a velocity of (32 ft/s)i- (7 ft/s)j and is 33 ft above the ground when it is hit by a 1.2-oz arrow traveling with a velocity of (165 ft/s)j + (230 ft/s)k where j is directed upwards. Determine the position P where the ball and arrow will hit the ground, relative to point O located directly under the point of impact.
