While working on the new Science building, the construction crew uses a bulldozer to push a large boulder across the site at a constant speed over a distance of 82.0 m. The boulder has a mass of 12700 kg and it slides across the ground with a kinetic coecient of friction k = 0.741.

a) draw and correctly label a free-body diagram for the boulder.

b) determine the amount of work done by all of the forces acting on the boulder.

c) determine the magnitude of the normal force extered by by the bulldozer on the boulder.
