A man pushes a 50 kg box up a 20-degree ramp at constant velocity. If the pushing force is parallel to the ramp, and the coefficient of friction is 0.4, how much force is he pushing with?
u=Fs, max/Fn Not sure if this equation is needed.
The Attempt at a Solution
I tried to solve the problem but I ended up getting the frictional force instead of the force he is pushing with.
