A 19.8 kg block is dragged over a rough, hor- izontal surface by a constant force of 180 N acting at an angle of angle 32.8? above the horizontal. The block is displaced 75.5 m and the coefficient of kinetic friction is 0.173. 19.8 kg ? = 0.173
Find the work done by the 180 N force. The acceleration of gravity is 9.8 m/s2 .
Find the magnitude of the work done by the force of friction.
Find the work done by the normal force.
What is the net work done on the block?
