## 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.
