A rocket engine consumes 114 kg of fuel per second. If the exhaust speed is 3780 m/s, calculate the thrust on the rocket in kN.

Answer :

Final answer:

The thrust on the rocket is 430.92 kN (kilonewtons).

Explanation:

To calculate the thrust on the rocket, we can use the formula:

Thrust = Fuel consumption rate * Exhaust velocity

Given that the fuel consumption rate is 114 kg/s and the exhaust velocity is 3780 m/s, we can substitute these values into the formula to get:

Thrust = 114 kg/s * 3780 m/s

= 430,920 N

The thrust on the rocket is 430,920 N, which is equal to 430.92 kN (kilonewtons).
