MR A pulley of mass 3M and radius R is mounted on ftictionless bearings and supported by a stand of mass 4M at rest on a table as shown to the right. The rotational inertia of this pulley about its axis is (3/2)MR2. Passing over the pulley is a massless cord supporting a block of mass M on the left and a block of mass 2M on the right. The cord does not slip on the pulley, so after the...

The pulley in the figure (Figure 1) has radius R and a moment of inertia I. The rope does not slip over the pulley, and the pulley spins on a frictionless axle. The coefficient of kinetic friction between block A and the tabletop is mu_k . The system is released from rest, and block B descends. Block A has mass m_A and block B has mass m_B Use energy methods to calculate the speed of block B as a function of the distance d that it has descended. Express your answer in terms of the variables m_A, m_B, R, I, mu_k, d and appropriate constants.
3 (15 points) The pulley in the figure has radius R and a moment of inertia I. The rope does not slip over the pulley, and the pulley spins on a frictionless axle. The system is released from rest, and the block descends. Block A has mass my, and block B ha mass mg. Use energy methods to calculate the speed of block B as a function of the distance d that it has descended. Your answer may contain R,...
A block of mass m is hanging from a cord that is wrapped around a pulley with radius R and moment of inertia I. When the block is released from rest, the pulley will rotate counterclockwise. Part A Solve for the acceleration of the block (your answer can include m,g,R, and I) Part B Draw a free body diagram showing the forces that act on the block Part C What happens to the acceleration of the block if the moment...
3. In the figure above, a spool or pulley with moment of inertia MR2 is hanging from a ceiling by a (massless, unstretchable) string that is wrapped around it at a radius R, while a block of equal mass M is hung on a second string that is wrapped around it at a radius r as shown. Find the magnitude of the acceleration of the the central pulley.

Two identical 1.0-kg blocks are connected by a massless string over a frictionless pulley of radius R = 6.000 cm and rotational inertia I = 0.003 kg m2 (see Figure).The string does not slip on the pulley, so the horizontal tension is different than the vertical tension. What is the magnitude of the angular acceleration of thepulley?
