projectile-motion

President Barbicane convenes the Gun Club members in Baltimore to announce a bold scientific project to reach the Moon, positioning it as a serious endeavor beyond previous fictional lunar voyages. He dismisses earlier theoretical communication attempts and proposes a practical plan to send a projectile to the Moon using artillery technology, supported by precise calculations and culminating in a formal proposal to test the experiment.

In this chapter, President Barbicane and the Gun Club consult the Cambridge Observatory to answer critical astronomical questions necessary for their moon projectile experiment. The observatory provides detailed scientific responses regarding the feasibility, timing, trajectory, and positioning required to successfully launch a projectile to the moon, emphasizing precise calculations of velocity, distance, and lunar positioning. The chapter concludes with a clear set of instructions and a timeline for the experiment, highlighting the importance of timing the launch to coincide with the moon's perigee and zenith crossing.

In this chapter, the committee discusses the technical challenges of constructing a massive cannon capable of launching a 20,000-pound projectile to the moon. Barbicane explains the physics involved, including air resistance, gravity, and the force of impulsion, and proposes a gun of unprecedented size and strength, made of cast iron and embedded in the earth. The chapter concludes with calculations of the cannon's enormous weight and cost, emphasizing the ambitious scale of the project.
