A 30 newton block is placed on top of a 100 newton block.  This arrangement is being pulled across the floor.  The coefficient of kinetic friction between the larger block and the floor is (0.50).  The coefficient of static friction between the two blocks is (0.75).  (Note that the weight, not the mass, of each block is given). Question:  What is the maximum horizontal force, F, that can be exerted on the lower larger block before the top block begins to slide off? (Draw the free body diagram of the bottom block and apply Newtons 2nd law to the bottom block).  Show the work on how the answer of 162 N is determined.
