A block of weight = 35.0 N sits on a frictionless inclined plane, which makes an angle theta = 27.0 with respect to the horizontal. A force of magnitude = 15.9 N, applied parallel to the incline, is just sufficient to pull the block up the plane at constant speed. What is Wg, the work done on the block by the force of gravity w as the block moves a distance L= 3.20 m up the incline? What is Wf, the work done on the block by the applied force as the block moves a distance L= 3.20 m up the incline?
