(17\%) Problem 4: The diagram shows a crate with mass $$m=37.3\mathrm{kg}$$ being pushed up an incline that makes an angle $$?=27.7^{?}$$ with the horizontal. The pushing force is horizontal, with magnitude $$P$$, and the coefficient of kinetic friction between the crate and the incline is $$?=0.33$$. Consider the work done on the crate as it moves a distance $$d=6.73\mathrm{m}$$ at constant speed. Hinte: dediction per hist. Hitis remaining 1 . A 2. 25 Part (b) What is the work, in joules, done by friction? 25 ?. Part (c) What is the work, in joales, donc by pravity? $$25\%$$ Part (d) What is the net work, in joules, done by the force P. friction and gravity? (Note that this is one apponach to the problem: Either we consider the work done by gravity, or, more commonly, we will consider the change in gravitabional potential energy.)
