A block of mass 5kg lies on a rough horizontal table. A force of 19.6 N is enough to keep the body sliding at uniform velocity. The coefficient of sliding friction is

A block of mass 5 kg rests on a rough horizontal surface. It is found that a force of 10 N is required to make the block just move However , once the motion begains, a force of only 8 N is enough to maintain the motion find the coefficient of kinetic and static friction between the block and the horizontal surface
