A Fe nucleus at rest emits a 14.0-keV photon. Use conservation of energy and momentum to deduce the kinetic energy of the recoiling nucleus in electron volts. (Use Mc2 = 8.60E-9 J for the final state of the Fe nucleus.)
what I have so far is...
E = pc because E >> photon rest energy , which = 0 eV
P = E/C = 7.476 E-24
P1 = P2
I'm not sure what to do next.
Thanks in advance for the help!
