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

A block of mass m slips on a rough horizontal table under the action of horiozontal force applied to it. The coefficient of friction between the block and the table is mu . The table does not move on the floor. Find the total frictional force aplied by the floor on the legs of the table. Do you need the friction coefficient between the table and the floor or the mass of the table ?
