= = Unwinding. A uniform spherical shell of mass M 4.5 kg and radius R 8.5 kg can rotate about a vertical axis on frictionless bearings. A massless cord passes around the equator of the shell over a pulley of rotational inertia I = 3.0 × 10-³kg. m² and radius r = 5.0 cm, and is attached to a small object of mass m = 0.60 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 80 cm after being released from rest? Use energy considerations.
