An electron is projected, with an initial speed of v= 2.18e+05 m/sec, directly towards a proton that is essentially at rest. If the electron is initially a great distance from the proton, at what distance from the proton is its speed instantaneously equal to twice its initial value? Express your answer in meters.

    The initial speed is different but the same equation can be used.
