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

`(ml)/(M+m)`

B

`(ml)/(2M)`

C

`(ml)/(M+2m)`

A rope thrown over a pulley has a ladder with a man of mass m on one of its ends and a counter balancing mass M on its other end. The man climbs with a velocity v_r relative to ladder. Ignoring the masses of the pulley and the rope as well as the friction on the pulley axis, the velocity of the centre of mass of this system is:

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 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 block of mass M is tied to one end of a massless rope the other end of the rope is in the hands of a man of mass 2M as shown in the figure the block and the man are resting on a rough plank of mass M as shown in the figure the whole system is resting on a smooth horizontal surface the man pulls the rope pulley is massless and friction what is the displacement of the plank when the block meets the pulley ( Man does not leave his position on plank during the pull)
