1. The problem statement, all variables and given/known data A 130 kg crate is pushed at constant speed up the frictionless 23° ramp shown in the figure. What horizontal force F is required? 2. Relevant equations F=ma F(parallel)=mgsin(theta) F(perpendicular)=mgcos(theta) 3. The attempt at a solution I know that because it is at a constant speed the net force equals zero, therefore the force caused by gravity equals the applied force. So first I solved the parallel force caused by gravity, which equals 498.2994 N. From there to create a net force of zero I flipped the sign, -498.2994 N. Solved for the horizontal component of that force: -498.2994cos23 =-458.687 N. But obviously that was not right. I think I might have to include the normal force by gravity in that equation too though. Any thoughts?
