Find the kinetic energies in eV of a free electron and an ion of 56^Fe, if both

Question

Find the kinetic energies in eV of a free electron and an ion of 56^Fe, if both have de Broglie wavelengths equal to the wavelength of visible light with frequency 3.85x10^14 1/s.

1 eV = 1.602 ? 10^-19 J
1 amu = 1.661 ? 10^-27 kg
me = 9.109 ? 10^-31 kg
h = 6.626 ? 10^-34 Js
c = 2.998 ? 10^8 ms

the kinetic energy of the electron (Ke) = 2.48
