8. From Eq. 37-49, the Lorentz factor is γ= + = + = 11 80 159 2 K mc MeV 135 MeV .. Solving Eq. 37-8 for the speed, we find γ γ = ¡ =− 1 1 1 1 2 2 vc a f which yields v = 0.778 c or v = 2.33 × 10 8 m/s. Now, in the reference frame of the laboratory, the lifetime of the pion is not the given τ value but is “dilated.” Using Eq.
