Position 0 Time (s) Two identical objects, A and B, move along straight, parallel, horizontal tracks. The graph above represents the position as a function of time for the two objects. (a) At approximately which time or times, if any, are the objects moving at the same speed? L the objects are never moving with the same speed during the interval shown, indicate this explicitly. Briefly explain your answer. (b) Describe what is happening to the positions of objects A and B between 3 seconds and 4 seconds. (c) Which object, if either, has an acceleration with a greater magnitude during the time interv shown in the graph? If the accelerations have the same magnitude for both objects, indicate this explicitly. (d) In a clear, coherent, paragraph-length response, explain your response to part (c). Be sure to reference and compare the graphed information for both objects A and B.
