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
instantaneous velocities and the instantaneous accelerations at t = 1
and t = 2 s.
(c) Compare the average and instantaneous quantities
and in each case explain why the larger one is larger.
