Three objects, a disk, a spherical shell and a hoop of similar mass, M=10.0 kg, and same radius, R=5.0 cm, are released at rest from the top of an incline which makes an angle of 30o with horizon. The length of the incline is 10.0 m.
a) What is their angular velocity at the end of the incline?
b) Which one reaches first down the incline? Describe why?
c) What is the speed of each object when they reach down the incline?
d) What is the ratio of rotational kinetic energy of each object to its translational kinetic energy?
