A block is pulled up a slope by a string that makes an angle of 30 with the slope, as shown in the figure below. The mass of the block is 8.0 kg. The slope makes an angle of 20 with the horizontal ground. The coefficients of kinetic and static friction between the box and the slope are y = 0.20 and Is = 0.30, respectively. The force exerted by the string on the box has a magnitude of 65 N. What is the net work done by all forces acting on the block if it moves a distance of 0.40 m up the slope?
