A positron is a particle with the same mass and magnitude charge as an electron, but a positron has a positive charge. If a positron and electron are held a distance of 0.900 pm apart and then both are released from rest, when they are 0.324 pm away from each other... (a) what is the system's total kinetic energy (i.e. what is the sum of the kinetic energies of both particles)? (b) how fast is the electron moving? m/s (c) how fast is the positron moving? m/s
