7 A stationary gun of mass 4.8kg mounted on wheels is in a battle field. It fires a bullet of mass 85g to the right with a velocity of v ms. The bullet moves horizontally and hits a stationary
wooden block of mass 5.6kg. It gets imbedded in the block. The bullet-block system then moves
a distance 10.78m and comes to rest in a time of 4.5 seconds.

In a game of pool, ball a is moving with a velocity v0 of magnitude v0 = 15 ft/s 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 assuming frictionless surfaces and perfectly elastic impact (that is, conservation of energy), determine the magnitudes of the velocities va, vb, and vc.
