Here it is:

You are pushing a box uphill the hill has a pitch of 15 degrees above the horizontal, and the static and kinetic friction coefficients between the box and the hill are 0.45 and 0.35. The box has a mass of 40 kg. You push horizontally with a push of 180 N, and the box is initially moving uphill. Find the acceleration of the box.

ANY HELP WOULD BE GREAT!!!
