Halliday, Resnick & Walker — Rotation: Problem Problem_83

In Fig. 10.22, two blocks, of mass \(m_1 = 400 \text{ g}\) and \(m_2 = 600 \text{ g}\), are connected by a massless cord that is wrapped around a uniform disk of mass \(M = 500 \text{ g}\) and radius \(R = 12.0 \text{ cm}\). The disk can rotate without friction about a fixed horizontal axis through its center; the cord cannot slip on the disk. The system is released from rest. Find (a) the magnitude of the acceleration of the blocks, (b) the tension \(T_1\) in the cord at the left, and (c) the tension \(T_2\) in the cord at the right.
