A block of weight w = 25.0 N sits on a frictionless inclined plane, which makes an angle θ = 20.0 ∘ with respect to the horizontal, as shown in the figure. (Figure 1)A force of magnitude F = 8.55 N , applied parallel to the incline, is just sufficient to pull the block up the plane at constant speed.

Part B

What is Wg, the work done on the block by the force of gravity w⃗  as the block moves a distance L = 5.00 m up the incline?

Part C

What is WF, the work done on the block by the applied force F⃗  as the block moves a distance L = 5.00 m up the incline?

Part D

What is WN, the work done on the block by the normal force as the block moves a distance L = 5.00 m up the inclined plane? a) Work done by gravity  the angle between gravity force and displacement is     b) Work done by applied force is the angle between applied force and displacement is 0 W = 42.75 J

c) Work done by the normal force The angle between the normal force and the displacement is 90 W = 0
