... This number is reasonable considering it took 1700 N to just keep the safe on the ramp not accelerating. It makes sense that it takes more force to accelerate it up the ramp. In that problem, we had a frictionless ramp, but what if we have to solve a problem that involves a ramp that is not friction ...
