A muon formed high in Earth's atmosphere travels at a speed 0.9900c for a distance (as we see it)of 9200 m before it decays.How far does the muon travel as measured in its frame?
A) 2596 m
B) 1298 m
C) 4554 m
D) 649 m

The distance measured in the muon's frame is contracted due to its high speed. Using the Lorentz contraction formula L = L0 * sqrt(1 - v^2/c^2), where L0 is the distance in Earth's frame (9200 m) and v = 0.9900c, the contracted distance L is approximately 1298 m.
