A 20-kg sphere 0.05 m in radius starts from rest and rolls (without slipping) 8.0 m down a ramp that is inclined at 30 degrees with the horizontal. (a) What is the angular speed of the sphere at the bottom of the slope if it starts from rest? (b)How much rotational kinetic energy does the sphere have at the bottom of the slope?
