Suppose you put your book bag on the table and want to move it out of the way so you can set up your laptop computer.  You push on the bag and it will not budge (The physics book is too big!).  If the bag's mass is 18 and the coefficient of friction with the table is 0.74, with what force or more will you have to push to make it move?  Give your answer in newtons (N).
