A uniform spherical shell of mass M = 17.0 kg and radius R = 0.310 m 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 = 0.210 kg·m2 and radius r = 0.100 m, and is attached to a small object of mass m = 1.50 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 a distance 0.859 m after being released from rest? Use energy considerations.

I am getting 1.39 but the system says it wrong
