Homework Statement
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
Homework Equations
F=mg to find the force that is pulling down on it
Fk= [itex]\mu[/itex] k Fn
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.
