A rope thrown over a pulley has a on one of its ends and a counterbalancing mass M on its other end. The man whose mass is m , climbs upwards by vec/_\r relative to the ladder and then stops. Ignoring masses of the pulley and the rope, as well as the friction the pulley axis, find the displacement of the centre of mass of this system.

A stationary pulley carries a rope whose one end supports a ladder with a man and the other end the counterweight of mass M. The man of mass m climbs up a distance l with respect to the ladder and then stops. Neglecting the mass of the rope and the friction in the pulley axle, find the displacement I of the centre of inertia of this system.

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.

A man of mass m is suspended in air by holding the rope of a ballon of mass M . As the man climbs up the rope, the ballon

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

A rope passess over a pulley which is sufficiently high. Two monkeys of equal mass climb the rope from opposite ends, one of them climbing quickly than the other relative to the rope. Assuming that the pulley and the rope are weightless and the rope is in extensible, which of monkeys will reach the top first?

A light rope is passed over a pulley such that at its one end a block is attached , and on the other end a boy is climbing up with acceleration g/2 relative to rope. Mass of the block is 30 kg and that of the boy is 40 kg. Find the tension and acceleration of the rope .

A man of mass M stands at one end of a stationary plank of length L, lying on a smooth surface. The man walks to the other end of the plank. If the mass of the plank is M//3 , the distance that the man moves relative to the ground is
