A 4.00 kg blоck is pulled 3.50 m аcrоss а hоrizontаl table by a constant applied force of 22.0 N directed at an angle of 30.0° above the horizontal. The coefficient of kinetic friction between the block and the table is 0.200. Use g=9.80 m/s2. A. Determine the work done by the applied force. Remember significant figures. Do NOT include units. ___ B. Determine the work done by friction. Remember that friction acts opposite the displacement. Do NOT include units. _ C. Determine the net work done on the block. Remember significant figures. Do NOT include units. _____
