A stack of books rests on a table. Each book has a different weight: the topmost book has weight W, the second book from the top has weight 2W, the third book from the top has weight 3W, and so on. In addition, someone pushes on the topmost book from above with force W. Let's say W = 2.5 Newtons. Question 3 Homework Answered Due Sep 11th, 11:59 PM What is the net force (N) on the fourth book, which has weight 4W? Type your numeric answer and submit Answered - Incorrect Question 4 Homework Unanswered Due Sep 11th, 11:59 PM How many Newtons are pointing upward on the same fourth book?
