Spherical and Disk Pulleys with Falling Mass Due in 1 hour, 44 minutes A uniform spherical shell of mass

M=2.50kg

and radius

R=32.0cm

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=2.00\times 10^(-3)kg*m^(2)

and radius

r=8.00cm

, and is attached to a small object of mass

m=2.00kg

. 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 2.00 m after being released from rest? Use energy considerations.
