Sure thing, but let’s get our math hats on first. First we need a clear goal: launch mass to the Moon, so we’re talking orbital velocity—about 11.2 km/s. That’s not a roller‑coaster speed; it’s rocket‑grade. We’ll break it into steps: 1. Energy calculation * Determine the kinetic energy per passenger: \(½mv^2\). * Convert that into a total energy budget for the coaster’s loop‑track segment. 2. Track design * Compute the radius needed for a safe centripetal force. * Use \(a_c = v^2 / r\) and keep \(a_c\) below roughly 4‑5 g for rider comfort. 3. Launch mechanism * Traditional coasters use compressed air or linear induction. * To reach 11 km/s you’d need a multi‑stage booster—essentially a small rocket, not a coaster. 4. Structural integrity * Material selection (high‑strength aluminum alloy or carbon‑fiber composite). * Fatigue analysis for the repetitive loading. 5. Safety systems * Redundant brakes, emergency parachutes, evacuation routes. * Fail‑safe telemetry to monitor velocity and acceleration in real time. 6. Regulatory checks * FAA/ESA launch licensing, environmental impact, public safety. So the “wild spirit” part can live in the visual design and theming—perhaps a moon‑crater look, a high‑speed drop—while the math keeps the ride grounded. If you really want lunar‑speed, we’re looking at a hybrid of coaster and launch vehicle, which turns the project into a space‑flight program. If that’s too much, let’s stick to the highest safe coaster speed on Earth—about 60–70 mph—and keep the moon dream for the imagination section.
