Board Pulled Out from under a Box - Copy A small box of mass 3.2kg is sitting on a board of mass 1kg and length 0.8m(Figure 1). The board rests on a frictionless horizontal surface. The coefficient of static friction between the board and the box is 0.56. The coefficient of kinetic friction between the board and the box is, as usual, less than 0.56. Throughout the problem, use 9.8m/s^2 for the magnitude of the acceleration due to gravity. In the hints, use Fr for the magnitude of the friction force between the board and the box. m Part A LG 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).
