A 5.00 kg box is pushed a distance of 15.0 m up a rough 20.0 degree incline with a constant force of 35.0 N. The coefficient of kinetic friction between the box and the surface is .60 and the box starts from rest. Calculate:
A. The kinetic energy of the box after moving 15.0 meters.
B. The work done by friction.
C. The work done by normal force.
D. The work done by the 35 N force.
