A rocket with a mass of 2.75×106 kg exerts a vertical force of 3.60×107 N on the gases it expels. Assume g remains constant for this problem, and ignore the mass of gas expelled (not realistic).
(a) Determine the acceleration of the rocket.
(b) Determine its velocity after 8.0 s.
(c) Determine how long it takes to reach an altitude of 9300 m.
