can anyone solve this?
A student moves a 35 kg box (343.2 N) up a ramp inclined at 12 degrees with respect to the horizontal. if the box starts at the bottom of the ramp and is pulled at 25 degrees with respect to the incline with a force of 185 N, what is the acceleration. uk=0.27. the answer is .9....but i need the work...i've tried for hours but i can't figure it out.

Have you drawn a free-body diagram?

Are you looking for acceleration up the ramp? I'm assuming yes...
