5. Consider the railgun system below. The bar has width xo, mass mo, and current lo provided by the DC current source, and starts at rest at y = 0. There is an external magnetic field Bo, and the rails are of length yo measured from the bar's initial position. Assume no gravity (z-dir anyway) or air resistance effects. Think of the xy-plane as a flat tabletop. (a) Draw the position and velocity of the bar over time, including what you expect happens just outside the rail gun. Assume no other forces, such as gravity and air resistance. Provide the expression for y. (One plot, one expression) (b) Suppose someone messes up and attaches an AC current source instead of a DC current source.What happens to the bar? (Short answer)
