Consider the collision of two identical particles, each of mass m0 . In experiment A, a particle moving at 0.950c strikes a stationary particle. (a) What is the total kinetic energy before the collision? (b) In experiment B, both particles are moving at the same speed u (relative to the lab), directly toward one another. If the total kineitc energy before the collision in experiment B is the same as that in experiment A, what is u? (c) In both experiments, the particles stick together. Find the mass of the resulting single particle in each experiment. In which is more of the initial kinetic energy converted to mass?
