Problem 4
A rocket of initial mass m = mₒ ejects its burnt fuel at a constant rate dm/dt = -rₒ and at a velocity vₒ (relative to the rocket). The rocket is in space and gravity can be ignored.
1. Calculate the initial acceleration a of the rocket.
2. The rocket exhausts its fuel when its mass is reduced to mጢ. Calculate the final velocity of the rocket vጢ.
