A small box of mass m, is sitting on a board of mass ma and length L (Eigure 1). The board rests on a frictionless horizontal surface. The coefficient of static friction between Part A the board and the box is . The coefficient of kinetic friction between the board and the box is, as usual, less than Find Fmin, 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). 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 the box. Express your answer in terms some or all of the variables 4, m1, m2. g. and L. Do not include f in your answer. > View Available Hint(s) ? Fain = Submit Provide Feedback
