Question

A rocket has a total mass of 1.01 10⁵ kg and a burnout mass of 1.14 10⁴ kg, including engines, shell and payload. The rocket blasts off from Earth and exhausts all its fuel in 4.31 min, burning the fuel at a steady rate with an exhaust velocity of v_e= 4.66 10³ m/s.

(a) If air friction and gravity are neglected, what is the speed of the rocket at burnout?
m/s

(b) What thrust does the engine develop at liftoff?
N

(c) What is the initial acceleration of the rocket if gravity is not neglected?
m/s²

(d) Estimate the speed at burnout if gravity isn't neglected.
m/s
