What is the recoil energy (in eV) of a 57Co nucleus
emitting a 14.4 keV gamma ray?
If anyone knows the equation that I can use, thanks.

Since the energy of the photon is small (i think it's not [itex] \gamma[/itex],are u sure it's not MeV...?),you can use the nonrelativistic formula for KE...
For a nice use of the total momentum conservation law ,assume the nucleus to be initially at rest.
