(13%) Problem 6: A rocket accelerates upward from rest, due to the first stage, with a constant acceleration of a1 = 89 m/s for t1 = 39 s. The first stage then detaches and the second stage fires, providing a constant acceleration of a2 = 32 m/s for the time interval t2 = 99 s. acceleration two a acceleration one a Otheexpertta.
