The diagram shows a crate with mass m = 38.2 kg being pushed up an incline that makes an angle φ = 26.6 degrees with horizontal. The pushing force is horizontal, with magnitude P, and the coefficient of kinetic friction between the crate and the incline is μ = 0.268. Consider the work done on the crate as it moves a distance d = 7.61 m at constant speed. What is work done by the pushing force, in joules?
