A tension force of 165 N inclined at 30.0o above the horizontal is used to pull a 27.0 kg packing crate a distance of 3.60 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. HINT (a) the work done by the tension force (in J) (b) the coefficient of kinetic friction between the crate and surface
