A rocket for use in deep space is to be capable of boosting a total load (payload plus the rocket frame and engine) of 3.15 metric tons to a speed of 10 000 m/s.

(a) It has an engine and fuel designed to produce an exhaust speed of 2 500 m/s. How much fuel plus oxidizer is required?

metric tons

(b) If a different fuel and engine design could give an exhaust speed of 7 500 m/s, what amount of fuel and oxidizer would be required for the same task?

metric tons
