How much of a single-stage rocket that is 100,000 kg can be anything but fuel if the rocket is to have a final speed of 8.00 km/s , given that it expels gases at an exhaust velocity of 2.20×103 m/s?

Step-by-step solution In this problem we have to calculate the mass of rocket after ejections. Step 1 of 3 The expression of velocity for rocket (in case of ejection of rocket single stage rocket) is, Here, is exhaust velocity, is initial mass, is remaining mass, is final velocity and is initial velocity. Step 2 of 3 Final velocity is, Substitute, for , 0 for , for and for in the expression of velocity,
