2018 F = ma Exam B — Question 15

You are standing on a weight scale that reads 700 Newtons while holding a large physics textbook that is originally at rest. At time t = 1 seconds you begin moving the textbook upward so that by time t = 2 seconds the textbook is now half a meter higher and once again at rest. Which of the following graphs best illustrates how the reading on the scale might vary with time?
