8. A yo-yo with mass M and radius R is wound with a light string. Someone drops it from rest with the string attached to a metal pole. The yo-yo falls and unwinds (spins) without slipping. The moment of inertia for the yo-yo is 2 MR (a disk). O a. Draw vectors showing all the forces acting on the yo-yo after it is released. b. In terms of g, find the downward acceleration of the center of mass of the yo-yo as it unrolls from the string. c. What is the tension in the string as the disk unwinds and falls? d. While descending, does the center of mass of the yo-yo move to the left, the right, or straight down? Explain your answer in complete sentences.
