6. A 4 kg wheel held in a frame of negligible mass rolls down a 22° ramp. The frame is attached to a massless string, which in turn is threaded over a pulley of 4 cm radius and 0.50 kg mass. The string is then wound around a uniform hollow spherical globe (shell) having a radius of 15 cm and a mass of 0.07 kg, rotates about its vertical axis on frictionless bearings. Assuming the wheel starts from rest, find its velocity after it has travelled a distance As = 15 cm down the ramp.
