90 points The system shown above is released from rest. The horizontal surface is frictionless, and there is sufficient friction for the uniform hoop to roll smoothly down the ramp. The hoop has a mass of 6.2kg and a radius of 27 cm. The pulley is a non - uniform disk with a mass of .25 kg, radius of 6.2 cm, and B = .38. The rope does not slip on the pulley. Determine the displacement of the box when the kinetic energy of the pulley is 443J.
