If the position of an object is given by x = (2.0 m/s3)t3 , find (a) the average velocity and the average acceleration between t = 1 and t = 2 s and (b) the instantaneous velocities and the instantaneous accelerations at t = 1 and t = 2 s.(c) Compare he average and instantaneous quantities and in each case explain why the larger one is larger.
