2. The average lifetime of a muon is about 2 µs. a) Estimate the average lifetime of a muon traveling at the speed of (i) 0.5 c, (ii) 0.9 c, (iii) 0.99 c. b) In a laboratory experiment, a muon is observed to travel a distance of 800 m before disintegrating. Estimate the speed of this muon in the laboratory frame.
