A 16.2 kg block is dragged over a rough, hor- izontal surface by a constant force of 80.2 N acting at an angle of 30.5 above the horizon- tal. The block is displaced 25.5 m. and the coefficient of kinetic friction is 0.196. 80.2 N 30.51 16.2 kg A = 0.106 Find the work done by the 80.2 N force. The acceleration of gravity is 9.8 m/s'. Answer in units of J
