A block of weight w = 25.0 N sits on a frictionless inclined plane, which makes an angle θ = 30.0 ∘ with respect to the horizontal, as shown in the figure. A force of magnitude F = 12.5 N applied parallel to the incline, is just sufficient to pull the block up the plane at constant speed. Part A The block moves up an incline with constant speed. What is the total work Wtotal done on the block by all forces as the block moves a distance L = 2.70 m up the incline? Include only the work done after the block has started moving at constant speed, not the work needed to start the block moving from rest. Part B What is Wg, the work done on the block by the force of gravity w⃗ as the block moves a distance L = 2.70 m up the incline?
