A large slab of mass 5kg lies on a smooth horizontal surface, with a block of mass 4kg lying on the top of it. The coefficient of friction between the block and the slab is 0.25. If the block is pulled horizontally by a force of F =6N, the work done by the force of friction on the slab, between the instants t=2s and t=3s, is (g=10ms^−2)
