A block weighing 67.5 Newton rests on a plane inclined at 25.0 degree to the horizontal. A force F is applied to the object at 45.0 degree to the horizontal, pushing it upward on the plane. The coefficients of kinetic and static friction between the plane and the block are, correspondingly, 0.156 and 0.354.

(a) Determine the minimum value of F that will prevent the block from slipping down the plane?

(b) Find the minimum value of F that will start the block moving up the plane?
