A 17 kg block is dragged over a rough, hor-
izontal surface by a constant force of 170 N
acting at an angle of angle 32.1◦ above the
horizontal. The block is displaced 33.9 m,
and the coefficient of kinetic friction is 0.199.
a] find the work done by 170N
b] find the magnitude of the work done by the force of friction
c] work done by the normal force
d] what is net work done by the block
