Oh really now? Its the maximum speed something can go before air friction stops its acceleration. While this generally pertains to falling objects, it can also apply to ballistics. Try again.
the velocity at which a falling body moves through a medium, as air, when the force of resistance of the medium is equal in magnitude and opposite in direction to the force of gravity.
the maximum velocity of a body falling through a viscous fluid.

Not to mention that friction also applies to tracks, not just the medium the objects are in (or lack thereof in the case of a vacuum).
So unless you can maintain a frictionless track (no small feat), and furthermore a frictionless track that can handle and still fully and properly direct infinite kinetic energy, not only such that it doesn't crash and burn, but also such that you don't have any diminishing returns from misdirected energy, then no, you would not have infinite acceleration.
Considering that terminal velocity is really just any condition in which a multitude of forces and conditions balance such that no more net acceleration can be achieved, then yes, it would reach such a condition under any real circumstances.
Terminal velocity does not just mean the point at which the force of gravity and force of friction of the atmosphere of a planet reach an equilibrium. It can refer to any two forces, or more than two forces.

The problem with that system is that you would need to remove the balls from the magnets after theyve been shot, and that takes energy, and there is the catch.
#13 - blergle (11/27/2012) [-]
What, so this occurs in a vacuum?
Nevermind the fact that there would be diminishing returns on being able to properly direct the energy to the point that eventually you'd lose all control and they'd fly off the track, thereby stopping you from having more cycles and capping the acceleration at your ability to control the exponentially increasing kinetic energy.
