A particle known as a pion lives for a short time before breaking apart into other particles.

Question:

A particle known as a pion lives for a short time before breaking apart into other particles. Suppose that a pion is moving at a speed of 0.990c, and an observer who is stationary in a laboratory measures the pion’s lifetime to be 3.5 × 10-8 s.

(a) What is the lifetime according to a hypothetical person who is riding along with the pion?

(b) According to this hypothetical person, how far does the laboratory move before the pion breaks apart?
