A large rocket has a mass of 2.00 10 6 kg at takeoff, and its engines

Question:

A large rocket has a mass of 2.00 × 10⁶ kg at takeoff, and its engines produce a thrust of 3.50 x 10⁷ N.

(a) Find its initial acceleration if it takes off vertically.

(b) How long does it take to reach a velocity of 120 km/h straight up, assuming constant mass and thrust?

(c) In reality, the mass of a rocket decreases significantly as its fuel is consumed. Describe qualitatively how this affects the acceleration and time for this motion.
