e.g. : Block A (m_A) is put on smooth table statically and connected with block B (m_B) with a light rope through a pulley (radius R , m_C) without friction. (1) What are the line acceleration of the two blocks? How much are the tension in level and vertical direction in the rope? (2) When B falls distance y, what is the speed? (3) If the friction of the pulley in bearing is not ignored and assume the torque is M_f What are the line acceleration and the?.

Consider two blocks (A and B) connected with a light rope passing over an ideal pulley, as shown to the right. The surface is horizontal, and the mass of block A is 10 kg, while the mass of block B is 2.0 kg. The coefficient of kinetic friction between the block and the surface is 0.15, while the coefficient of static friction between that block and the surface is 0.35. Once the blocks have been set in motion, find the tension in the rope and the magnitude of the blocks' acceleration.

Block 1 with mass m1=2.0 kg and is on a rough horizontal surface. A massless rope connects block 1 to block 2 of mass m2= 3.0 kg. Block 2 is on a frictionless surface tilted at Θ = 35 degrees. The coefficient of friction between block 1 and the horizontal surface is 0.30. The pulley is massless and frictionless. a. (14) What is the magnitude and direction of the acceleration of the blocks? b. (11) What is the tension in the string?

A block m resting on a rough horizontal table is attached by a rope to another block M such that the rope goes over a pulley and M hangs vertically over the edge of the table. The pulley is in the shape of a solid cylinder of mass 2m. When released from the rest, the blocks move with an acceleration of 1.3 m/s^2. What is the ratio of M/m? Assume the coefficient of friction is 0.2 and ignore frictional torque in the pulley.
