A block of weight w = 20.0N sits on a frictionless inclined plane, which makes an angle theta = 30.0^\circ with respect to the horizontal, as shown in the figure. (Figure 1) A force of magnitude F = 10.0N , 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 W_total done on the block by all forces as the block moves a distance L = 4.20m 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 W_g, the work done on the block by the force of gravity w_vec as the block moves a distance L = 4.20m up the incline? Part C) What is W_F, the work done on the block by the applied force F_vec as the block moves a distance L = 4.20m up the incline? Express your answer numerically in joules. Part D) What is W_N, the work done on the block by the normal force as the block moves a distance L = 4.20m up the inclined plane? Express your answer numerically in joules.
