Ayo-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. find the linear acceleration and angular acceleration of the yo-yo and the tension in the string.
