Question

An elementary particle called a pi meson (or pion for short) has anaverage lifetime of 2.6 *10^-8 s when at rest. I need help withPart C.

Part A

If a pion moves with a speed of 0.96 relative to Earth, find theaverage lifetime of the pion as measured by an observer on Earth.Express your answer using two significant figures.
=9.3×10-8 (Correct)


Part B

Find the average distance traveled by the pion as measured by thesame observer.
Express your answer using two significant figures.
=27 (Correct)


Part C??

Find how far would the pion have traveled relative to Earth ifrelativistic time dilation did not occur.
Express your answer using two significant figures.
