(3%) Problem 17: The diagram shows a crate with mass m = 31.3 kg being pushed up an incline that makes an angle = 29.7" with the horizontal. The pushing force is horizontal, with magnitude P, and the coefficient of kinetic friction between the crate and the incline is 4 = 0.41. Consider the work done on the crate as it moves a distance d = 6.98 m at constant speed. $ 25% Part (a) What is work, in joules, done by the pushing force, P?
