A muon is created 50 km above the surface of the earth. In theearth's frame, the muon is traveling directly downward at0.9999c.
Part A
In the earth's frame of reference, how much time elapses betweenthe muon's creation and the time it reaches the surface?
Part B
Use time dilation to determine, in the muon's frame, how muchtime elapses between the muon's creation and the time it reachesthe surface.
Part C
In the muon's frame of reference, length contraction reduces thedistance between the point at which it is created and the surfaceof the earth. What is this distance?
