What would be the terminal velocity of the rod if all the conditions of part (b) of the problem where held, except there was also friction with a kinetic coefficient of Hk = 0.0215? Qualitatively discuss what effect considering the resistance of the conducting rails would have on your estimate of terminal velocity. Make sure to consider that as the rod slides, the overall resistance of the circuit increases as a function of that distance slid. Do you think this would lead to a larger or smaller terminal velocity than the one you calculated in part (b)?
