A rocket accelerates by burning its onboard fuel, so its mass decreases with time. Suppose the initial mass of the rocket at liftoff (including its fuel) is m, the fuel is consumed at rate r, and the exhaust gases are ejected with constant velocity ve (relative to the rocket). A model for the velocity of the rocket at timet is given by the equation v(t) = -gt - Ve In m - rt where g is the acceleration due to gravity and t is not too large. If g = 9.8 m/s2, m = 32,000 kg, r = 190 kg/s, and ve = 3,000 m/s, find the height of the rocket one minute after liftoff. (Round your answer to the nearest whole meter.)

Expert Solution
Step 1

The given equation states the vertical speed of the rocket.

Hence, by integrating it with respect to time (t), the rocket’s vertical position (y) may be determined as follows:
