(a) determine the rotential inertia of a yo-yo about it's center.
(b) derive using force and torque. the expresion for the linear acceleration of a yo-yorolling down the string.
(c) the calculate the acceleration on the center of mass of the yo-yo given the following R disk =2.5 cm R axle = 0.25 cm M disk = 25 g M axle = 0.75 g.
