A body of mass m is slowly hauled up a rough hill as shown in fig by a force F which acts tangential to the trajectory at each point. Find the work performed by the force, if the height of hill is h, the length of its base l and coefficient of friction between the body and hill surface is m. What is the work done if body is moved along some alternative path shown by the dotted line, friction coefficient being same.

A block of mass m is slowly carried on a inclined plane by a force F which always acts along the tangent to the plane. If the co-efficient of friction between the block and incline be mu , then work done by force of friction while carrying block from bottom of the plane to the top will be :

A small block of mass m os takes slowly up a fixed hemisphere from P to Q and then slowly down along its surface from Q to S by force F , which at each point of the surface, is tangential to the surface. If the coefficient of friction is mu , then the work performed by the force F in taking the block from P to S along the hemispherical surface of radius R is :
