In a game of pool, ball A is moving with a velocity v0= v0i when it strikes balls B and C, which are at rest side by side. Assuming frictionless surfaces and perfectly elastic impact (that is, conservation of energy), determine the final velocity of each ball, assuming that the path of A is
(a) Perfectly centered and that A strikes B and C simultaneously,
(b) Not perfectly centered and that A strikes B slightly before it strikesC.
Three masses are placed at different points along a meter stick of negligible mass: 0.09 kg at 0.98 m, 0.04 kg at 0.55 m, Where's the center of mass of the system
