Are you saying to break up Fa into x and y components so that Fax = (Fa)(sin 30°) and Fay = (Fa)(cos 30°)?
If not, then I'm afraid I don't know how to write it in terms of Fa and θ.
Thank you for your response haruspex.
The question doesn't state if he's pushing up or down at 30 degrees, so I will assume he is pushing up. By a horizontal and vertical forces, do you mean that the force applied (Fa) and the normal force (Fn) are the horizontal forces and the force of gravity...
Homework Statement
Albert is pushing a 1.8 kg book against a vertical wall at an angle of 30.0 degrees. If the coefficient of static friction is 0.47 and kinetic friction is 0.35, how hard does Albert need to push the book to allow it to slide down the wall at a constant speed?
