Homework Statement
A proton has a mass of 938 MeV/c2. Calculate the speed, momentum, and total energy of a 1760 MeV proton.
Homework Equations
E= mc^2 (Rest Energy)
E= Ɣmc^2 (Total Energy)
p= Ɣmv (momentum)
KE= mc^2(Ɣ-1) (Kinetic Energy)
The Attempt at a Solution
I'm not sure how the last number given (1760 MeV) is relevant, as in, I don't know what to do with it in order to start solving the problem. I know it isn't rest energy/mass because that is given as 938 MeV/c^2. It also is not the total energy because that is asked for in the question and the answer is not 1760 MeV.
