S S (13%) Problem 6: A rocket accelerates upward from rest, due to the first stage, with a constant acceleration of a = 89 m/s for t = 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. 33% Part (a) Enter an expression for the rocket's speed, v, at time t in terms of the variables provided.
