Suppose an unstable particle with a rest mass of 10 GeV/c² travels at a speed of 0.8c with respect to an observer. The particle decays into two smaller particles with rest masses of 3 GeV/c² and 5 GeV/c² respectively. What are the velocities of the two resulting particles, and what is the kinetic energy released in the decay process?
