A uniform spherical shell of mass M = 3.40 kg and radius R = 29.0 cm can 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 = 4.00x10" kg.me and radius r = 10.0 cm, and is attached to a small object of mass m = 3.00 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 when it has fallen 8.00 m after being released from rest? Use energy considerations.
