Suppose the mass of a rocket just as it runs out of fuel is 75400-kg, and its exhaust speed is 2.25 × 103 m/s. Calculate the maximum rate, in kilograms per second, at which the rocket can expel gases, if its acceleration cannot exceed seven times that of the gravitational acceleration on the surface of the Earth. Assume the gravitational force on the rocket is negligible.
