The relationship introduced in Problem 1-37 has been interpreted to mean that a particle of mass m(E=m c^2) can materialize from nothing provided that it returns to nothing within a time Δt ≤h / m c^2 . Particles that last for time Δt or more are called real particles; particles that last less than time Δt are called virtual particles. The mass of the charged pion, a subatomic particle, is 2.5 ×10^-28 kg . What is the minimum lifetime if the pion is to be considered a real particle? | Numerade

SOLVED:An unstable particle called a positive pion (pronounced "pie-on") decays in an average time of 2.6 ×10-8  s. On average, how long will a positive pion last if it is traveling at 95 % of the speed of light?
