SUMMARY
The minimum rate of fuel consumption for a rocket with an exhaust speed of 8.0 km/s and an initial mass of 6.0x106 kg, required to achieve a vertical acceleration of 8.0 m/s2, is calculated using Newton's Second Law. The thrust force is determined to be 4.8x107 N. The correct fuel consumption rate is found to be 6000 kg/s, but this value is identified as incorrect due to the misunderstanding that the force calculated is the net force rather than the actual thrust produced by the rocket motor.
