Consider the collisions of two identical particles, each of mass m0. In experiment A, a particle moving at 0.9c strikes a stationary particle.

(a) What is the total kinetic energy before the collision?

(b) In experiment B, both particles are moving at a speed u (relative to the lab), directly toward one another. If the total kinetic 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 ldnetic energy converted to mass?
