# I need help with an AP Physics 1 FRQ?

Here is the FRQ, the attached image is the graph it refers to:

Two identical objects, A and B, move along straight, parallel, horizontal tracks. The graph attached as the image 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? If 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 interval 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 graph information for both objects A and B.
