Homework Statement
A beam of unknown particles travels at a speed of 2.5 x 10^8 m/s. When the particles are moving at this speed, their average lifetime is found to be 7,3 x 10^-8 s. What is their average lifetime when at rest?
Homework Equations
Well, Lorentz transformation for time is an obvious one: t = t'*[itex]\gamma[/itex]
The Attempt at a Solution
Well, I really have no idea where to pick this from. I know that when v = 0 => t = t'.
I'm missing something here...
Thanks in advange.
