A rope is utilized to pull a 3.57 kg block at constant speed 4.86 m along a horizontal floor. The force on the block from the rope is 7.82 N and is directed 15° above the horizontal.
a) What is the work done by the rope's force?
b) What is the increase in the thermal energy of the block-floor system?
c) What is the coefficient of kinetic friction among the block and floor?
