Two bodies with masses `m_1` and `m_2(m_1gtm_2)` are joined by a string passing over fixed pulley. Assume masses of the pulley and thread negligible. Then the acceleration of the centre of mass of the system `(m_1+m_2)` is

Two bodies with masses m_1 and m_2 , (m_1>m_2) are joined by a massless string passing over a fixed pulley.The downward acceleration of mass m_1 is :

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

Two masses m and M(m lt M) are joined by a light string passing over a smooth and light pulley (as shown)

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.

Two blocks of mass m_(1)"and"m_(2) are connected by light inextensible string passing over a smooth fixed pulleuy of negligible mass. The acceleration of the centre of mass of the system when blocks move under gravity is :

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.
