A solid cylinder has a total mass,M, of 90 kg. It has an outer radius,R, of .95 meters and an inner radius,r, of .091 meters. A string is attached to the cylinder which a cat is holding on. The cat has a mass of 70 kg and is descending to the ground with an initial height of 12.2 meters. Determine the velocity of the cat when (y=0) in m/s.

Please show the solution step by step.
