An object of mass m slides down a hill of height h and of arbitrary shape and stops at the bottom because of friction. The coefficient of friction may be different for different segments of the path. Work required to return the object to its position along the same path by a tangential force is

An object of mass m slides down a hill of arbitrary shape and after travelling a certain horizontal path stops because of friction. The total vertical height descended is h . The friction coefficient is different for different segments for the entire path but is independent of the velocity and direction of motion. The work that a tangerial force must perform to return the object to its initial position along the same path is

A block of mass 1 slides down a curved track that is one quadrant of a circle of radius 1m. Its speed at the bottom is 2m/s. The work done by frictional force is:

A small block of mass m ,slides down a smooth incline plane of height h and moves some distance on rough horizontal surface before coming to rest.The coefficient of friction between block and horizontal surface is mu .The minimum work to be done on the block to it move it back to original position along the same path is: 1) mgh 2) 2mgh 3) 3mgh 4) (1+mu)mgh

An object of mass m is slowly pushed some partway up a verticle up a verticle loop ending at a point a height h lt R above the bottom. The coefficient of friction between the object and the track is a constant mu. Find work that has to be done against friction.

A body of mass 0.5 kg is taken up an inclined plane of length 10 m and height 5 m and then allowed to slide down to the bottom again. The coefficient of friction between the body and the plane is 0.1. The work done by the frictional force over the round trip is
