The Pi Meson An elementary particle called a pi meson (or pion for short) has an average lifetime of 2.6 x 10 s when at rest. Part A Suppose a pion moves with a speed of 0.92 c relative to a stationary laboratory. If there were NO RELATIVISTIC effects, how far would the pion travel in the laboratory before decaying. Express your answer using two significant figures. day = m Submit Previous Answers Request Answer X Incorrect; Try Again; 5 attempts remaining Part B However, because of relativity the pion's lifetime as seen in the laboratory will be longer. By what factor will the lifetime of the pion increase when moving at a speed of 0.92 c. ( y) Submit Request Answer
