Question

When at rest, muons (?) have a half-life of 2

When at rest, muons (?) have a half-life of 2 times 10?6s. One thousand muons at a particle accelerator are moving at a very high speed such that after 200 times 10?6s, 250 muons have not decayed. According to an observer at rest with respect to the accelerator, what is the half-life of these muons? What is the value of ? for these muons? For an observer moving with the muons, how much time did it take for the number of muons to reach 250? How many meters did the muons travel in the accelerator lab before 500 of them would have decayed?
