While moving in, a new homeowner is pushing a box across the floor at a constant velocity. The coefficient of kinetic friction between the box and the floor is 0.424. The pushing force is directed downward at an angle below the horizontal. When is greater than a certain value, it is not possible to move the box, no matter how large the pushing force is. Find that value of 0.
