A 20.0 kg solid cylinder, 0.25m in radius, and a 5.0 kg thin hollow sphere,
0.50 m in radius, are released from rest at the exact same time at the top of a
10m long ramp inclined at 30º.
a) What is the final velocity of the cylinder at the bottom of the ramp?
b) What is the final velocity of the sphere at the bottom of the ramp?
c) Which will reach the bottom first? By how many seconds?
