A large rocket has a mass of 2.00×106kg at takeoff, and its engines produce a thrust of 3.50×107 N . (a) Find its initial acceleration if it takes offvertically. (b) How long does it take to reach a velocity of 120km/h straight up, assuming constant mass and thrust? (c) Inreality, the mass of a rocket decreases significantly as its fuelis consumed. Describe qualitatively how this affects theacceleration and time for this motion
