An 800-N box rests on a plane inclined at 30 to the horizontal. A physics student finds

Question:

An 800-N box rests on a plane inclined at 30° to the horizontal. A physics student finds that she can prevent the box from sliding if she pushes on it with a force of at least 200 N parallel to the surface.

(a) What is the coefficient of static friction between the box and the surface?

(b) What is the greatest force that can be applied to the box parallel to the incline before the box slides up the incline?
