A set of eight boxes, 5.0 kg each, are stacked on top of a table, as shown in the figure below. (a) Draw a FBD of the top-most box and find the normal force exerted on it by the box below. (b) Draw a FBD of the 2nd box from the top, including all three (!) forces acting on it. Find the normal force acting on this box by the box below it. (c) Do you see a pattern now? Draw a FBD of the lowest box, including all three forces acting on it. What is the normal force that the table exerts on this box?
