Steel ball is dropped onto a hard floor from a height of 1.50 m and rebounds to a height of 1.45 m.
(a) calculate its velocity just before it strikes the floor.
(b) calculate its velocity just after it leaves the floor on its way back up.
(c) calculate its acceleration during contact with the floor if that contact lasts 0.0800 ms (8.00×10−5s).
(d) how much did the ball compress during its collision with the floor, assuming the floor is absolutely rigid?

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.
