An 18.3 kg block is dragged over a rough, hor- izontal surface by a constant force of 107 N
acting at an angle of 26.3° above the horizon-
tal. The block is displaced 6.77 m, and the
coefficient of kinetic friction is 0.208.

1. Find the work done by the 107N force. the acceleration of gravity is 9.8 m/s
Answer in J.

2. Find the magnitude of work done by the force of friction
