Problem
A 2.5 kg block slides down a rough plane inclined at 30° above the horizontal. The coefficient of kinetic friction between the block and the surface is 0.20. Using g=9.8m/s2, determine the magnitude and direction (up or down the incline) of the net force acting on the block along the surface.
