(3%) Problem 17: The diagram shows a crate with mass m = 25.9 kg being pushed up an incline that makes an angle = 24.2 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 = 6.88 m at constant speed
