In a game of pool, ball A is traveling with a velocity v0 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 v0 = 4 m/s and vC = 2.1 m/s, determine the magnitude of the velocity of

(a) Ball A,

(b) Ball B.
