How would one calculate the velocity of a 1MeV neutron?? I tried the following the attached formula for V/C but E is less than the rest mass which yields the square root of a negative number. Not sure what to do for this
It doesn't say. I guess that I will assume such. Is the 'E' in the equation I am using for the rest mass energy plus the kinetic energy?
Since a neutron has a higher rest mass than 1MeV, then one should safely assume that kinetic energy is what is meant here. The E in that equation is indeed the rest+kinetic energy.
Since the neutron rest mass is approximately 940 Mev, you probably could use E=(mv^2)/2 to get v. (v=c/22?).
