A spring of spring constant 50. N/m is hanging from a retort stand. A second spring of spring constant 100. N/m is hanging from the bottom of the first spring. A mass of .50 kg is hung from the bottom of the lower spring at rest. Determine:
(a) the overall stretch of the spring combination
(b) the 'effective' spring constant of the spring combination
(c) a general expression for the spring constant of any combination of two springs connected in this manner

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.
