2011 F = ma Exam — Question 2

Questions 2 to 4 refer to the three graphs below which show velocity of three objects as a function of time. Each object is moving only in one dimension. 0 2 4 6 8 10 −2 0 +2 +4 velocity (m/s) time (s) 0 2 4 6 8 10 −2 0 +2 +4 velocity (m/s) time (s) 0 2 4 6 8 10 −2 0 +2 +4 velocity (m/s) time (s) Object I Object II Object III 2. Rank the magnitudes of the average acceleration during the ten second interval.
