Hi all,(adsbygoogle = window.adsbygoogle || []).push({});

I need help with question

I need to calculate the work done in pushing a mass up an incline a distance d with slope theta, when the coefficient of kinetic friction is 0.1 and the force is directed 1) parallel to the slope, 2) the force is directed at an angle phi to the slope?

I know that when ignoring friction the work done is is given by mgh, where h=d*sin(theta). However I'm getting confused on how to determine the problem with the additional forces.

can anyboby offer some tips on how i could solve this problem.
