A 19.6 kg block is dragged over a rough, horizontal surface by a constant force of 162 N acting at an angle of 28.9 ◦ above the horizontal. The block is displaced 23.1 m, and the coefficient of kinetic friction is 0.237. 19.6 kg µ = 0.237 162 N 28.9 ◦ Find the work done by the 162 N force. The acceleration of gravity is 9.8 m/s. Answer in units of J.
