A block of mass 0.4kg is pulled along the curve path CAN slowly by a tangential force as shown in figure. The work done by the applied force when the block moves from A to B is

A block of mass 1 kg is pulled slowly along the curve path ACB by a tangential force as shown in figure. The magnitude of work done by the frictional force when the block moves from A to B is

A block of mass 1 kg is pulled slowly along the curve path ACB by a tangential force as shown in figure. The magnitude of work done by the frictional force when the block moves from A to B is

A block of mass 2 kg is pulled along circular arc from position X to Y as shown in figure. The work done by the horizontal force is pulling the block from X to Y is

A block of mass 2 kg is released from rest on a rough inclined ground as shown in figure. Find the work done on the block by a) gravity b) force of friction .when the block is displaced downward along the plane by 2m ? . (Take g 10 m//s^(2) ).

A block is constrained to move along x axis under a force F=-(2x)N . Find the work done by the force when the block is displaced from x=2 m to x = 4m

A 5 kg block moves in a straight line on a horizontal frictionless surface under the influence of a force that varies with position as shown in the figure. Find the work done by this force as the block moves from the origin to x = 8m.
