In a game of pool, ball A is moving with a velocity vo when it strikes balls B and C, which are at rest and aligned as shown. Knowing that after the collision the three balls move in the directions indicated and that vo = 12 ft/s and vc = 6.29 ft/s, determine the magnitude of the velocity of 1. ball A (7 points) 2. ball B (8 pоints)
