The sheer amount of energy required to launch a payload at 2km/s from such a short barrel would require a current far in excess of anything THIN copper wire could bear. Not only would the barrel burst and copper go flying everywhere, the copper would be molten.
You don't know much about physics do you?
All the wire has to do is carry the amperage it's being fed. The energy is generated by a variation in magnetic flux. This has absolutly nothing to do with melting the wire. If the amperage is high enough, yes the wire could overheat, but since it's so long, I don't think you need that much current.
