A 20.0 kg box (200 N) rests on an incline.  The surface makes an angle of 22.62° with the horizontal and has µk= 0.62 and µs= 0.81.

A)         A horizontal force with a magnitude of 400 N acts on the box.  Does the box move?  If not, why not?  If it does, what is its acceleration?

B)         What minimum horizontal force is required to keep the box from sliding down the incline?
