If a body has kinetic energy. T, moving on a rough horizontal surface stops at distance y. The frictional force exerted on the body is

A body of mass m, having momentum p, is moving on a rough horizontal surface. If it is stopped in a distance x, the coefficient of friction between the body and the surface is given by

A block of mass m is moving on a rough horizontal surface. mu is the coefficient of kinetic friction between the block and the surface. What is the net force exerted by the surface on the block?

A body of mass m is kept on a rough horizontal surface of friction coefficient m . A force P is applied horizontally , but the body is not moving .Find the net force F excerted by the surface on the body .
