A 160-lb block is pulled up by a constant force P through a cable to move up the inclined surface with a constant acceleration of a = 6 ft/s2. The coefficient of kinetic friction between the block and the inclined surface is HK = 0.25. The angle between the cable and inclined surface as shown is 0 = 40°. Neglect size of the block, (Figure 1) Figure 1 of 1
