## A rail gun accelerates a projectile from rest by using the magnetic force on a current-carrying wire.The wire has radius and is made of copper having a density of . The gun consists of rails of length L = 1.00 m in a constant magnetic field of magnitude B = 2.00 T,oriented perpendicular to the plane defined by the rails. The wire forms an electrical connectionacross the rails at one end of the rails. When triggered, a current of flows through thewire, which accelerates the wire along the rails. Calculate the final speed of the wire as it leaves the rails.
