Group Exercise -- Punkin' Chunkin

[Punkin' chunkin']
This weekend marks the 12th year of the Punkin' Chunkin' contest in Lewes, DE. The object of this contest is to propel, without use of explosives, an 8 to 10 pound pumpkin as far as possible; last year's record was 2,710 feet set by an air cannon from Illinois. There are several categories available: catapult, centrifugal, human-powered, youth, and longest overall toss.

I propose a new category -- electromagnetic toss. Using the principles of PHYS208 (and PHYS207), design a punkin' chunkin' rail capable of a one-mile toss. Be as specific as possible, taking into consideration physical properties of the pumpkin, ballistics as realistic as possible, and energy sources and dissipation. Remember that your device will be firing in the middle of a cornfield...
