A uniform spherical shell of mass M = 2.0 kg and radiusR = 13.0 cm rotates about a vertical axis on frictionlessbearings (see the figure). A massless cord passes around theequator of the shell, over a pulley of rotational inertia I =1.92×10-3 kg m2 and radius r = 4.0cm, and its attached to a small object of mass m = 4.0kg. There is no friction on the pulley's axle; the corddoes not slip on the pulley. What is the speed of the object afterit has fallen a distance h = 1.1 m from rest: Use work -energy considerations.
