Poloy wants to determine the muzzle velocity of his home-made potato launcher. For the experiments conducted by Poloy on a level test range, the potato launcher muzzle is set to a height of 1.2m from the ground with a launch angle of 45 degrees with respect to the horizontal. After three trials, the average range of the potato projectile is 74.3 m on level ground. Determine the muzzle velocity of the potato launcher.

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.
