Serway & Jewett β Rotation of a Rigid Object about a Fixed Axis: Problem 41
Review. A string is wound around a uniform disk of radius \(R\) and mass \(M\). The disk is released from rest with the string vertical and its top end tied to a fixed bar (Fig. P10.41). Show that (a) the tension in the string is one third of the weight of the disk, (b) the magnitude of the acceleration of the center of mass is \(2g/3\), and (c) the speed of the center of mass is \((4gh/3)^{1/2}\) after the disk has descended through distance \(h\). (d) Verify your answer to part (c) using the energy approach.
