(7%) Problem 12: The diagram shows a crate with mass $m = 27.3$ kg being pushed up an incline that
makes an angle $\phi = 22.2$ degrees with horizontal. The pushing force is horizontal, with magnitude $P = 576$
N. Starting from rest, the crate achieves a speed of 4.83 m/s as it moves a distance $d = 6.84$ m.
What is the work done by friction, in joules?
