Homework Help: Fast protons

  1. Nov 4, 2007 #1
    A proton emits a flash of light every meter of its own (proper) time. Between successive flash emissions, each proton travels a distance specified as recorded by a lab observer. Find the momentum, Energy, Time stretch (gamma), and lab time between flashes for the specified values.

    2. Relevant equations

    (proper time)^2 = (lab time)^2 - (lab distance)^2

    Energy = rest mass + kinetic energy

    Energy = restmass * lab time/proper time = restmass * gamma

    3. The attempt at a solution

    I am asking this question because I get the same values for Energy, Gamma, and Lab Time. I also get that the momentum should be equal to the lab distance. This doesn't feel right and am looking for a double check. Thanks!
