A metal ball with a mass of 3.77·10^-6 kg and a charge of +4.79 mC has a kinetic energy of 6.21·10^8 J. It is traveling directly at an infinite plane of charge with a charge distribution of +4.05 C/m^2. If it is currently 1.39 m away from the plane of charge, how close will it come to the plane before stopping? Please note that the ball is 1.39 away.
