There are six books in a stack, each with a weight of 3.0 N. The coefficient of friction between all the books is 0.20 as is the coefficient between the table and the bottom book. What horizontal push must I just exceed on the next to bottom book to start sliding the top five books off the bottom one?
 a. 1.0 N
  c. 3.0 N
