Consider the situation as shown in the figure. The boy of mass `M` holds the light rope and the system is at rest. If `m` is mass of the box, find the force exerted by the boy on the rope and contact force beteween the boy and the box.

Consider the situation as shown in the figure. The system is free to move. The force by the rope on the block is FM//(M+m)

In the previous problem if M=80kg and m=410kg and the boy pulls the rope such that the system (boy+box) moves upward with acceleration 5m//s^(2) ,find the force exerted by the boy and contact force between the boy and the box.

A boy of mass 50 kg standing on ground exerts a force of 500 N on the ground. The force exerted by the ground on the boy will be :

A man of mass 60kg is standing on a massless weighing machine. Find the weight of the man in different situations as shown in the following figures. Man holds the rope and the block is at rest. Man holds the rope and the system is at rest. Man holds the rope and the system is at rest.

A uniform rope of mass m hangs freely from a ceiling. A bird of mass M climbs up the rope with an acceleration a. The force exerted by the rope on the ceiling is

A uniform rope of mass m hangs freely from a ceiling. A bird of mass M climbs up the rope with an acceleration a. The force exerted by the rope on the ceiling is

In the arrangement shown in the figure, the pulley has a mass 3m, Neglecting friction on the contact surface, the force exerted by the supporting rope AB on the ceiling is
