A sodium ion is placed at the point halfway between 16.46 and 12.1, and then released from rest. What will be its speed after it has traveled a distance of 45 km from where it was released? Assume it didn't bump into anything along the way, including any atoms or other charged particles, and ignore any effects that could be attributed to earth's gravity or magnetic field. In other words, keep the doggone problem simple! I've given you enough to think about just to be able to figure out the mass of a sodium ion!
