A block of mass is pulled along a rough horizontal surface by a rope as shown in the figure below. The tension in the rope is and the force of friction between the block and the surface is . If the block travels a distance of along the surface in , find:
(a) the work done by the tension in the rope.
(b) the work done by the force of gravity.
(c) the work done by the normal force.
