A 19.5 kg block is dragged over a rough, hor- izontal surface by a constant force of 133 N acting at an angle of angle 34.3° above the horizontal. The block is displaced 74.4 m and the coefficient of kinetic friction is 0.197. 133 N 34.3 19.5 kg μ = 0.197
Find the work done by the normal force.
What is the net work done on the block? Answer in units of J.
