Homework Statement
An Omega- particle has rest energy 1672 MeV and mean lifetime 8.2X10-11 s. It is created and decays in a particle track detector and leaves a track 24mm long. What is the total energy of the Omega- particle?
Homework Equations
E=E0/Sqrt(1-v^2/c^2)

The Attempt at a Solution
I took the distance and divided by time and found the V would be .967c. Once that was used to then find E. The answer was off. The correct answer was 2330 MeV. I don't know how they got that. My answer was 7678 MeV.
