In the figure, two blocks, of mass m1 = 308 g and m2 = 378 g, are connected by a massless cord that is wrapped around a uniform disk of mass M = 513 g and radius R = 11.1 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...

In the figure, two 5.60 kg blocks are connected by a massless string over a pulley of radius 2.20 cm and rotational inertia 7.40 times 10^-4 kg-m^2. The string does not slip on the pulley; it is not known whether there is friction between the table and the sliding block; the pulley's axis is frictionless. When this system is released from rest, the pulley turns through 1.00 rad in 179 ms and the acceleration of the blocks is constant. What...

A m_1 = 14.0 kg object and a m_2 = 12.0 kg object are suspended, joined by a cord that passes over a pulley with a radius of 10.0 cm and a mass of 3.00 kg (Fig. P10.46). The cord has a negligible mass and does not slip on the pulley. The pulley rotates on its axis without friction. The objects start from rest 3.00 m apart. Treating the pulley as a uniform disk, determine the speeds of the two...
