SUMMARY
The forum discussion focuses on calculating the exit velocity of a cylindrical projectile launched from an air cannon. The user has gathered essential parameters including dimensions, volumes, distance, time of flight, air pressure, and launch angle. A suggested method involves using the range equation: range = (v^2 * sin(2 * angle)) / gravity, leading to v = sqrt((range * gravity) / (sin(2 * angle))). However, caution is advised regarding the impact of drag on the projectile's flight, as standard equations assume zero drag, which may lead to significant errors in calculations.
