A box of mass m = 10 kg sits on a table. The coefficient of kinetic friction is 0.2 between the table and the box. A force of F = 40 N is applied to it horizontally so that the box is moving along the table. a) Calculate the work done by the friction force when the box is displaced 3 m along the direction of its motion. b) What about the work done by the gravitational force? c) The work done by the applied force?
