Some time, delta T, after a rocket blasts off from the surfaceof earth, it is travelling at a constant speed, and itsinstantaneous mass(including fuel) is M+20,000kg. The gas ejectedout the back of the rocket is moving at a relative velocity of1,200 m/s (downward), with respect to the rocket. You may assumethat the rocket is still very close to the surface of the earth,and that air resistance is negligible. A) What is the rate of fuelconsumption at this moment in time? (What rate is the rocket losingmass?) I know the answer is -163kg/s I just dont understand howthey got that answer. Thanks!
