In
1980, over San Francisco Bay, a large yo-yo was released from a
crane. Suppose the yo-yo was 195 kg, and it consisted of two
uniform disks of radius 37.2 cm connected by an axle of radius 3.72
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?
