A 17.9 kg block is dragged over a rough, horizontal surface by a constant force of 174 N acting at an angle of 33.7 above the horizon- tal. The block is displaced 5.79 m, and the coefficient of kinetic friction is 0.156. 174 N 33.7 17.9 kg = 0.156 Find the work done by the 174 N force. The acceleration of gravity is 9.8 m/s. Answer in units of J. Answer in units of J. part 2 of 2 Find the magnitude of the work done by the force of friction. Answer in units of J. Answer in units of J.
