    "abstract": "The relativistic addition of parallel velocities is derived involving\nrelativity only via the time dilation formula, avoiding the length contraction\nused by many authors in conjunction with time dilation. The followed scenario\ninvolves a machine gun that fires successive bullets, considered from its rest\nframe and from the rest frame of the target, the bullets hit.",
