A hollow ball (I=2/3 MR^2) of radius 7 cm and mass of 0.2kg starts from rest and rolls without slipping down a ramp. After the ball has dropped a vertical distance of 0.3 meters, what is its angular speed? Air resistance and losses due to friction may be neglected.

A hollow sphere of mass m = 0.35 kg and radius r = 64 cm rolls along a flat surface at an initial speed of v, and then up a curved ramp with radius of curvature 4.7 m without slipping, until it reaches a maximum angle of 12 degrees around the curve and starts to roll backward. What was the initial speed of the ball in units of meters/second?
