A 40.0-kg box initially at rest is pushed 5.00 m alonga rough, horizontal floor with a constant appliedhorizontal force of 130 N. The coefficient of friction between box and floor is 0.300. Find (a) the work doneby the applied force, (b) the increase in internal energyin the boxfloor system as a result of friction, (c) thework done by the normal force, (d) the work done bythe gravitational force, (e) the change in kinetic energyof the box, and (f) the final speed of the box.
