Question

A rocket of mass m exhausts gases at a rate r = (dm/dt) with a velocity verelative to the rocket.
(A) Minimum value of r so that thrust on rocket is sufficient to overcome gravity is Ve >
(B) If ve and rare constant then the acceleration of the rocket will remain constant
(C) If ve and r are kept constant, the rocket will move with an acceleration of varying magnitude
(D) If ra 2mg then the rocket will take off with an upward acceleration equal to g in magnitude Ve​
