# In 1980, over San Francisco Bay, a large yo-yo was released from a crane. Suppose the yo-yo was 105 kg, and it consisted of two uniform disks of radius 39.6 cm connected by an axle of radius 3.96 cm. What was the magnitude of the acceleration of the yo-yo during (a) its fall and (b) its rise? (c) What was the tension in the cord on which it rolled?
