A uniform spherical shell of mass M = 3.0kgand radius R = 13.0cmcan rotate 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 = 1.36�10 -3 kg�m 2 and radius r = 4.0cm, and is attached to a small object of mass m = 1.0kg. There is no friction on the pulley’s axle; the cord does not slip on the pulley. What is the speed of the object when it has fallen 1.5mafter being released from rest? Use energy considerations.
