A small box of mass mi is sitting on a board of mass my and length L (Figure 1). The board rests on a frictionless horizontal surface, The coefficient of static friction between the board and the box is 4g. The coefficient of kinetic friction between the board and the box is, as usual, less than s. I Review | Constants Part A Throughout the problem, use g for the magnitude of the free-fall acceleration. In the hints, use f for the magnitude of the friction force between the board and Find Fnin, the constant force with the least magnitude that must be applied to the board in order to pull the board out from under the the box (which will then fall off of the opposite end of the board). the box. Express your answer in terms of some or all of the variables g, m1, m2, g, and L. Do not include f in your answer.
