The graph shows the momentum y\n, in newton-seconds, of an object x\n seconds after the object started moving, for 0≤x≤8. What is the average rate of change, in newton-seconds per second, in the momentum of the object from \n\tx\n\t=\n\t2\n\n to \n\tx\n\t=\n\t6\n\n?

","rationale_html":"

The correct answer is 12. For the graph shown, x\n represents time, in seconds, and y\n represents momentum, in newton-seconds. Therefore, the average rate of change, in newton-seconds per second, in the momentum of the object between two x-values is the difference in the corresponding y-values divided by the difference in the x-values. The graph shows that at \n\tx\n\t=\n\t2\n\n, the corresponding y-value is 6\n. The graph also shows that at \n\tx\n\t=\n\t6\n\n, the corresponding y-value is 8\n. It follows that the average rate of change, in newton-seconds per second, from \n\tx\n\t=\n\t2\n\n to \n\tx\n\t=\n\t6\n\n is 8-66-2, which is equivalent to 24, or 12. Note that 1/2 and .5 are examples of ways to enter a correct answer.
