A spring of spring constant k placed horizontally on a rough horizontal surface. It is compressed against a block of mass m which is placed on rough surface, so as to store maximum energy in the spring. If the coefficient of friction between the block and the surface is µ, the potential energy stored in the spring is: (block does not slide due to force of spring.)
