A block of mass m = 5.0 kg is pulled along a rough horizontal surface by a

Question:

A block of mass m = 5.0 kg is pulled along a rough horizontal surface by a rope as sketched in Figure P6.8. The tension in the rope is 40 N, and the coefficient of kinetic friction between the block and the surface is μ_K= 0.25.?

(a) If the block travels a distance of 4.5 m along the surface, what is the work done by the rope??

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