How fast must a pion be moving on average to travel 30 m before it decays?...
How fast must a pion be moving on average to travel 30 m before it decays? The average lifetime, at rest, is 2.6×10-8 s.
Homework Answers
The above question is solved using the
concept of length contraction because it is a relativistic case(i.e
particle move with velocity comparable to speed of light)

2. The pion has an average lifetime of 26.0ns when at rest. For it to travel 10.0m, how fast must it move? Throughout this homework assignment, you may use e to denote the speed of light in both your work and final answers without using its numerical value. (This is actually preferred unless the problem requires the numerical value of e.)

A pion is an unstable particle that has a mean lifetime of 2.55 x 10^-8 s. Thi si the time interval between its creation in a nuclear process and its extinction into decay products, as measured in a frame of reference at rest with respect to the pion. An average pion is traveling at 0.230 c relative to Earth. How far does it travel in its lifetime, relative to Earth?
