A rocket engine moving at 500 m/s produces a total thrust of 9563 N, consuming propellants at the rate of 4.55 kg/s. The energy content of the propellants is 5.35 MJ/kg. Find the effective exhaust velocity.

A rocket engine moving at 500 m/s produces a total thrust of 9563 N, consuming propellants at the rate of 4.55 kg/s. The energy content of the propellants is 5.35 MJ/kg. Find the effective exhaust velocity. Correct Answer 2100 m/s

Rocket thrust is the product of mass flow rate and effective exhaust velocity. Using this, ue = T/m = 9563/4.55 ≈ 2100 m/s.
