Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

A launch vehicle has 6 engines operating in parallel which are fed from the same propellant tank. Initially, each engine has an equivalent exhaust velocity of 3500 m/s and consumes 400 kilograms of propellant per second. One of the engines malfunctions and consequently operates at 50% thrust and 120% propellant consumption. Calculate the equivalent exhaust velocity in m/s of all engines if treated as a single engine, including the malfunctioning engine in your calculation.
