Lunar Fireworks: Ballistic Display

Description

This lecture discusses the ballistic display of fireworks on the moon, where astronauts celebrate their arrival by launching fireworks. The lecture covers the explosion of a firework projectile, calculating the time of explosion, the trajectory of fragments, and the energy involved. It also explores the impact points on the lunar surface and the relationship between the additional mechanical energy and the initial kinetic energy of the projectile.
