Back to 28.3 Length Contraction

28.3 Exercise 7

Avg difficulty 2.5

(a) How far does the muon in the reference travel according to the Earth-bound observer? (b) How far does it travel as viewed by an observer moving with it? Base your calculation on its velocity relative to the Earth and the time it lives (proper time). (c) Verify that these two distances are related through length contraction γ=3.20\gamma= 3 . \text{20}.
