A particle starts from X = 9.4 m at t = 0 and moves along the x-axis. A graph of the particle's velocity as a function of time is shown in the figure, where the vertical axis is scaled such that vs = 6.13 m/s. What is the difference between the instantaneous acceleration at t = 1 s and the average acceleration over the time interval from t = 0 to t = 5 s? (Give your answer in m/s^2.)
