Homework Statement
Determine how accurately you will need to measure the speed of a particle that has energy 2 GeV to determine whether it is a pion (mass = 0.14 Gev/c^2) or a Kaon (mass = 0.49 Gev/C^2). *This question is in a relativity section, so I'm assuming relativistic equations are neccesary*
Homework Equations
[tex]
E^2 = (p^2)(c^2) + (m^2)(c^4)
[/tex]
[tex]
p = (\gamma)mv
[/tex]
The Attempt at a Solution
I started by substituting [tex] p= (\gamma)mv [/tex] into the other equation so velocity can be related to mass, but I'm lost as to what the basic approach to this problem would be.
