Catapult: Physics of Projectile Motion

This lecture covers the physics of a catapult, which consists of a beam that can rotate around a fixed point, with a counterweight and a projectile. The beam accelerates the projectile before it follows a ballistic trajectory. Equations for the beam angle, projectile motion, detachment angle, and landing distance are derived. The lecture also discusses the moment of force, kinetic moments, and the landing conditions of the projectile.
