The atomic nucleus, flying out of the accelerator at a speed of 0.4 s, after a time t = 1.47 μs, emitted a beta particle in the direction opposite to its movement at a speed of 0.8 s relative to the nucleus. How long after the departure of the nucleus does the beta particle enter the accelerator outlet?
