Example 10: A man stacks a small block of wood on top of a larger block and then moves both by pushing the bottom block. The large block has a mass of 45 kg , and the smaller block has a mass of 25 kg . The coefficient of static friction between the two blocks is 0.45 . What is the maximum acceleration of the blocks without having the smaller block slide off the top? Hint: Ask yourself, if both blocks are accelerating together, what forces pulling the top block
