What is the purpose of Distance X in a projectile's trajectory?

The purpose of Distance X in a projectile's trajectory is to represent the maximum distance a projectile will travel under specific conditions. This distance is crucial for determining how far the projectile will go based on various variables such as the angle of launch, the velocity, and environmental factors like air resistance. Understanding this distance allows safety personnel and operators to ensure that they are firing in a controlled environment, preventing any inadvertent harm to people or property outside the designated area. By accurately gauging this distance, range safety officers can effectively manage and secure the firing range, ensuring that all necessary safety protocols are in place.
