Question 1. The speed of light is 2.998 * 10 ^8 m/s. Find the ratio of the total energy to the rest energy of a particle of rest mass m0 moving with speed 0.26 c.
Question 2. The K^0 particle has a mass of 497.7 MeV/c^2 . It decays into aPi- and Pi+, each with mass 139.6 MeV/c2 . Following the decay of a K^ 0, one of the pions is at rest in the laboratory. Determine the kinetic energy of the K^ 0 prior to decay.
