A 19.6 kg block is dragged over a rough, horizontal surface by a constant force of 148 N acting at an angle of 30.7° above the horizontal. The block is displaced 64.7 m, and the coefficient of kinetic friction is 0.185. Find the work done by the 148 N force. The acceleration of gravity is 9.8 m/s^2. Answer in units of J. Find the magnitude of the work done by the force of friction. Answer in units of J.
