A hollow cylinder, a solid cylinder, and a billiard ball are all released at the top of a ramp and roll to the bottom without slipping.

PART A Rank them according to the fraction of the kinetic energy that is rotational as they roll. billiard ball/ solid cylinder/ hollow cylinder

PART B What are the ratios of speeds of a hollow and a solid cylinders when they reach the bottom of the ramp?

PART C What are the ratios of speeds of a hollow cylinder and a billiard ball when they reach the bottom of the ramp

PART D What are the ratios of speeds of a solid cylinder and a billiard ball when they reach the bottom of the ramp?

A solid cylinder of radius 25cm is released from rest at the top of a smooth 4degree incline of height h=5m. At the same time and from the same position, a hollow sphere of radius 25 cm is also released from res. Both objects roll without slipping and both objects have a mass of 75g. How long did it take for the faster of the two objects to reach the bottom of the hill?
