A 20.0 kg box is pulled up a ramp a distance d = 15.0 m with a force of Fp = 165 N parallel to the ramp, as shown in the figure to the right. The coefficient of kinetic friction between the box and ramp is µk = 0.225, and the ramp is at an angle of ? = 30.0° above the horizontal

a) Find the work done on the block by the normal force.

b) Find the work done on the block by the kinetic frictional force.

c) Find the work done on the block by gravity.

d) Find the work done on the block by the pulling force, Fp.
