This question is the calculation version of the previous one (dragging a heavy box up a ramp). Again, remember that the "normal force" or "perpendicular force" is just a name for the force a surface exerts on an object, in a direction perpendicular to the surface.  You're dragging a 43 kg box up a ramp that forms a 30 degree angle relative to the level ground. What is the magnitude of the normal force between the box and the ramp in Newtons?
