A block is pulled up a slope by a force Fp = 65 N (parallel to 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 μk = 0.20 and μs = 0.30, respectively. 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?
