A yo-yo is made from two uniform disks, each with mass m and radius R, connected by a light axle of radius b. A light, thin string is wound several times around the axle and then held stationary while the yo-yo is released from rest, dropping as the string unwinds.
Part A: Find the acceleration of the yo-yo (Express your answer in g, b, R, m)
Part B: Find the angular acceleration of the yo-yo (Express your answer in g, b, R, m)
Part C: Find the tension in the string (Express your answer in g, b, R, m)
