Calculate the magnitude of the average acceleration aaverage during this trip. m/s? daverage = Is it possible to determine whether the acceleration was uniform from the information given in the problem? Yes, because the acceleration is equal to the change in velocity divided by the change in time. O No, because an intermediate velocity is needed to determine whether the acceleration is uniform. No, because there is not enough information to determine the acceleration at every instant during the time interval. O Yes, because the acceleration always points in the same direction according to the figure.
