A `50 kg` person stand on a `25 kg` platform. He pulls on the rope which is connected to the rope which is attected to the plateform `via` the frictionless pulley as shown in the figure. The platform moves upwards at a steady rate if the force with which the person pulls the rope is

A 50 kg person stand on a 25 kg platform. He pulls on the rope which is connected to the rope which is attached to the platform via the frictionless pulley as shown in the figure. The platform moves upwards at a steady rate if the force with which the person pulls the rope is

A man of mass m stands on a frame of mass M. He pulls on a light rope, which passes over a pulley. The other end of the rope is attached to the frame. For the system to be in equilibrium, what force must the man exert on the rope?

A block of mass M is pulled down along a horizontal frictionless surface by a rope of mass m. If a force F is applied at one end of the rope, the force which the rope exerts on the block

A man with mass 85 kg stands on a platform with mass 25 kg. He pulls on the free end of a rope that runs over a pulley on the ceiling and has its other end fastened to the platform. The mass of the rope and the mass of the pulley can be neglected, and the pulley is frictionless. With what force does he have to pull so that he and the platform have an upward acceleration of 2.2m/s^(2) . (Take g= 10m/s^(2) )
