A pulley fixed to the ceiling carries a string with blocks of mass `m` and `3m` attached to its ends. The masses of string and pulley are negligible .When the system is released, its center of mass moves with what acceleration

A pulley fixed to the ceiling carries a thread with bodies of masses m_(1) and m_(2) attached at its ends. The masses of the pulley and thread are negligible, friction is absent. Find the acceleration of the centre of mass (a_("cm")) of this system.

A pulley fixed to the ceiling carries a thread with bodies of masses m_1 and m_2 attached to its ends. The masses of the pulley and the thread are negligible, friction is absent. Find the acceleration w_C of the centre of inertia of this system.

Two blocks of masses 6 kg and 4 kg are attached to the two ends of a massless string passing over a smooth fixed pulley. if the system is released, the acceleration of the centre of mass of the system will be

Two masses 2 kg and 3 kg are attached to the end of the string passed over a pulley fixed at the top. The tension and acceleration are

A pulley fixed to the ceiling of an elevator car carries a thread whose ends are attached to the loads of masses 3m and m . The car starts gong up with acceleration g//s . Assuming the masses of the pulley and the thread, as well as friction, to be negligible, find the force exerted by the pulley on the ceiling of car.

A disc shaped pulley of mass 'm'=4 kg and radius R=0.5m can rotate freely about its center. A block of mass M=2kg hangs from the pulley through is massless string that is tightly wrapped around the pulley. When the system is released, there is no slipping between pulley and string. (a) Calculate the angular accelerating of the pulley (b) Calculate the tension in the string

A thin uniformed rod of mass m and length L is hinged at one end and from other end a light string is attached. The string is wound over a frictionless pullely (having mass 2m ) and a block of mass 2m is connected to string on other side of pulley as shown. the system is released from rest when the rod id making an angle of 37^(@) with horizontal. Based on above information answer the following question : Just after releases of the system from rest acceleration of block is

In Fig. 6-29, a 2.0 kg block is placed on top of a 3.0 kg block, which lies on a frictionless surface. The coefficient of kinetic friction between the two blocks is 0.30, they are connected via a pulley and a string. A hanging block of mass 10 kg is connected to the 3.0 kg block via another pulley and string. Both strings have negligible mass and both pulleys are frictionless and have negligible mass. When the assembly is released, what are (a) the acceleration magnitude of the blocks, (b) the tension in string 1, and (c) the tension in string 2?
