A block of mass m = 5.0 kg is pulled along a rough horizontal surface by a rope as sketched in the figure below. The tension in the rope is 80 N, and the coefficient of kinetic friction between the block and the surface is ?K = 0.15.

(a) If the block travels a distance of 7.0 m along the surface, what is the work done by the rope?

(b) Find the work done by friction on the block.
