A uniform spherical shell of mass M = 3.0kg and radius R = 12.0 cm rotates about a vertical axis on frictionless bearings (see the figure). A massless cord passes around the equator of the shell, over a pulley of rotational inertia I = 2.38×10-3 kg m2 and radius r = 5.0 cm, and its attached to a small object of mass m = 1.0 kg. There is no friction on the pulley's axle; the cord does not slip on the pulley. What is the speed of the object after it has fallen a distance h = 1.0m from rest: Use work - energy considerations.
