A yoyo is a toy made of three uniform density disks with a string wrapped around the middle disk. The middle disk has a mass m and radius T,' the outer disks each have mass M and radius R. The string has negligible mass and stretches a negligible amount. Analyze the following situation. As the yoyo is moving downward, you pull up with a constant force F and as you pull, your hand moves upward a distance I). At the beginning of your move the yoyo was headed downward with speed '01 and angular speed wl. When your hand has moved up a distance b, the yoyo has moved down a smaller distance h and has speed '02 downward and angular speed 002 . Assume that the string doesn't slip or rub against the outer disks, so there is no change in temperature of the yoyo. downward R 4-'// M M w 2 Side view \f
