Solving a problem in physics section 52 point 49 mechan

49. In an inelastic collision particles having momentum p = m0c, and the same particle at rest in a composite particle. To determine: 1) the velocity υ particles (in terms of a) before the collision; 2) the relativistic mass of the particle component (in units m0); 3) the rate of the composite particles; 4) the rest mass of the composite particle (in units m0); 5) the kinetic energy of the particle before the collision, and the kinetic energy of the composite particles (in units m0s2).
