1. The problem statement, all variables and given/known data The average lifetime of muons at rest is τμ0 = 2.2 μs. A laboratory measurement on the decay in flight of muons in a beam emerging from a particle accelerator yields an average lifetime of τμ = 6.6 μs, as measured in the lab frame Σ. (g) [3 points] Given a large ensemble of these muons, some of the muons will travel farther than others in the laboratory frame Σ. The average distance traveled is the number you found in part (f). Graph the distribution of the distances traveled in the laboratory frame Σ by this ensemble of muons. Carefully label your axes, and show both horizontal and vertical scales. 2. Relevant equations Δx = βcτμ = 1881 m for average distance part (f) 3. The attempt at a solution I'm missing some point what is happening in such ensemble. Please give me some hint. Thank you.
