A tension force of 165 N inclined at 30.0 above the horizontal is used to pull a 33.0 kg shipping crate a distance of 4.10 m on a rough surface. If the crate moves at a constant speed, find (a) the work done by the tension force and (b) the coefficient of kinetic friction between the crate and surface.
