[SOLVED] Restmass, lifetime of a meson

1. The problem statement, all variables and given/known data

A [tex]\rho[/tex] meson is a highly unstable subatomic particle with a rest mass of 776 MeV/c^2 and a mean lifetime of [tex]4\times10^{-24}[/tex]s. What is the minimum uncertainty in the meson's energy?

2. Relevant equations

We know that rest energy of a particle E = mc^2, m being rest mass I'm assuming.

3. The attempt at a solution

I don't even know where to begin. I'm not sure what they're asking, and what it is I need to calculate.

Doc Al

I suspect that they want you to apply the so-called energy-time uncertainty principle. Look it up!
