For rocket propulsion, the velocity of exhaust gases relative to the rocket is \(2\) km/s. If the mass of a rocket system is \(1000\) kg, then the rate of fuel consumption for the rocket to rise with an acceleration \(4.9\) m/s² will be:
1. \(12.25~\text{kg}/\text{s} \)
2. \(17.5~\text{kg}/\text{s} \)
3. \(7.35~\text{kg}/\text{s} \)
4. \(5.2~\text{kg}/\text{s} \)
