Homework Help: physics

a yo-yo of mass 440kg measuring 0.9m in radius was dropped from a platform 63m high. One end of the string was tied to the platform, so the yo-yo unwinds as it descends. Assuming the axle of the yo-yo has a radius of 0.2m, find the velocity of descent at the end of the fall. The acceleration of gravity is 9.81 m/s^2.
