Question:
A yo-yo has weight W and radius of gyration kO. If it is released from rest, determine how far it must descend in order to attain angular velocity ω. Neglect the mass of the string and assume that the string is wound around the central peg such that the mean radius at which it unravels is r. Solve using the conservation of energy.
