1. The problem statement, all variables and given/known data A 250N force is directed horizontally to push a 29kg box up a plane that is inclined at 27 degrees to the horizontal. the box moves up the plane at a constant speed. Determine the magnitude of the normal force, and the coefficient of kinetic friction. g=9.8m/s^2 a(y) = 0m/s 2. Relevant equations F=mg to find the force that is pulling down on it Fk= [itex]\mu[/itex] k Fn 3. The attempt at a solution I understand that the forces need to be resolved into the same direction, but i'm not sure what direction the normal force would be pointing in. The force of gravity i got was 284.2N. I can't figure out the kinetic friction until i figure out the normal force.
