(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A box is being pulled up a ramp with a force F. The ramp has a 30 degree incline with the horizontal. write the sum of the forces in the x direction and y direction. Make the x and y coordinate system be parallel and perpendicular with the ramp.

3. The attempt at a solution

Ok so my sum of forces in the x direction (parallel to the ramp) is

F_pull - F_gx = ma

Force of the pull minus force of gravity on the box in the x direction equals mass times accel.

My sum of forces in the y direction (perp. to the ramp) is

n = mg

Normal force equals mass times accel due to gravity

I am having trouble grasping this. Please help me understand :)

Thank you
