A block weighing 72.5 N rests on a plane inclined at 25.0° to the horizontal. A force F is applied to the object at 45.0° to the horizontal, pushing it upward on the plane. The coefficients of static and kinetic friction between the block and the plane are, respectively, 0.372 and 0.156.

(a) What is the minimum value of F that will prevent the block from slipping down the plane? Your response differs from the correct answer by more than 10%. Double check your calculations.

(b) What is the minimum value of F that will start the block moving up the plane? Your response differs from the correct answer by more than 100%.

(c) What value of F will move the block up the plane with constant velocity?
