Homework Help: Relativistic Kinetic Energy & Gamma

  1. Oct 10, 2011 #1
    1. The problem statement, all variables and given/known data

    (7.) If its kinetic energy is 3000 MeV, find its speed as a multiple of c. In this case you cannot use the nonrelativistic approximation.

    m=4000 MeV/c^2 (rest energy=4000MeV)
    ^from previous problem, of which this one is a continuation

    2. Relevant equations

    KE=(γ-1)mc^2

    3. The attempt at a solution

    since v is only present in the gamma equation, I figured I'd have to solve for it there? The negatives in the ensuing algebra don't seem right.

    (KE/MC^2)+1=1/(√1-(v2/c2))
