4. A 270 N force is applied horizontally to a 40kg box which rests on a rough horizontal surface and the box moves 7 m. The kinetic friction force between the surface and the box is 30 N. Calculate: a) The work done on the box by the applied force. b) The work done on the box by the normal force. c) The work done on the box by the friction force. d) The net force acting on the box. e) The net work done on the box.
