2. The coefficient of static friction between all contacting surfaces is μ = 0.4. The weight of each box is the same, W, and the center of gravity of each box is at its geometric center. a) Determine the minimum horizontal force P needed for the top box to be on the verge of sliding across the top of the lower box (be sure to provide a free body diagram). Is this situation physically possible? b) Determine the minimum horizontal force P needed for both boxes to tip together (be sure to provide a free body diagram).
