2. The engine of a rocket in outer-space, far from any planet, is turned on. The rocket ejects burned fuel at a constant rate; in the first second of firing, it ejects 1/120 of its initial mass at a relative speed of 2,400 meters per second.
What is the rocket’s initial acceleration?
A. Calculate the rate at which it burns its fuel (in the notes it is the term “m-dot”).
B. Calculate the exhaust velocity. Assume the exhaust velocity is constant.
C. Calculate the maximum velocity the sounding rocket will obtain.
