Homework Statement
What force would you have to exert on a 326-N trunk up a 21.0° inclined plane so that it would slide down the plane with a constant velocity? What would be the direction of the force? (The coefficient of friction between the plane and the trunk is 0.322.)
Homework Equations
not sure what to use by
Ff=coefficient friction *Fn
The Attempt at a Solution
Ihave tried drawing a picture of this
but what i done is
figure that the Fw=326N
from there I am not sure where to use it or what equations to
