As shown in the figure below, a box of mass m = 55.0 kg (initially at rest) is pushed a distance d = 82.0 m across a rough warehouse floor by an applied force of F = 30 N.
(a) Work done by the applied force WA = J
(b) Work done by the force of gravity Wg
(c) Work done by the normal force WN
(d) Work done by the force of friction Kr J
(e) Calculate the net work on the box by finding Whet = net force
(f) Now find the net work by first finding the net force on the box, then finding the work done by Wuet = J
