Re: How Far Can A Locomotive Jump? And, with enough speed

Since the OP asked about jumping a locomotive, presumably over something Evel Kneivel style, it's even simpler than all these equations: forces at right angles can't act on each other.
This means that the moment the locomotive (or whatever) leaves what is supporting it against the force of gravity (the tack), it immediately starts falling, and this downward motion is independent of it's forward motion. Thus, if the landing point is at the same (or higher) elevation as the lift off, FAIL, no matter how fast it goes. It the landing is lower, then you have to start appling them formulae.
If a locomotive is to jump a gap, it must be provided with some force acting against gravity to impart some upward motion. This is usually done with a ramp, like what Knievel uses to jump his motorcycles over _____ (fill in the blank with items of your choice).
In order to get the locomotive to the moon, you'll have to ask Ralph Kramden.
