Chapter 08, Problem 045

A rope is used to pull a 5.16 kg block at constant speed 6.62 m along a horizontal floor. The force on the block from the rope is 4.47 N and directed 10.5° above the horizontal. What are (a) the work done by the rope's force, (b) the increase in thermal energy of the block-floor system, and (c) the coefficient of kinetic friction between the block and floor?
