A large rocket has a mass of 1.91 ✕ 106 kg at takeoff, and its engines produce a thrust of 3.43 ✕ 107 N.   (a) Find its initial acceleration (in m/s2) if it takes off vertically. (Enter the magnitude.)  m/s2     (b) How long does it take (in s) to reach a velocity of 264 km/h straight up, assuming constant mass and thrust? s   (c) In reality, the mass of a rocket decreases significantly as its fuel is consumed.
