A CHALLENGE

I hereby issue a challenge to all you gents who keep telling me
how dumb I am --- let's see you solve this problem (as I have).
First, we use as the mass of the photon, Einstein's version: m = L/c^2
(If you insist the photon has no mass, you are hereby excused --- go
somewhere else.)
THE PROBLEM
We have m_1, the mass of a photon ---
and we have m_2, the mass of a ponderous particle.
m_1 = m_2
We now want to equate the kinetic energy of the photon to that of the
particle.
To restate: At what velocity will the kinetic energy of the particle
(E_k) equal
the kinetic energy of the photon?
Use a 1 MeV photon --- and an electron as the particle.
NOTE: Not fair to gerrymander the result.
A METHOD MUST BE SHOWN FOR ANY PAIR OF MASSES.
(On second thought, this may be easier than I had supposed.)
