This confirmed that the whole asteroid is made of homogeneous titanium. At that point, an accident occurred when one of the little green men fell off the surface of the asteroid into the trial shaft. He fell, without any braking, until he reached O, when he died on impact. However, work continued and the little green men started secret excavation of the titanium, in the course of which they formed a spherical cavity of diameter AO inside the asteroid, as illustrated in the figure. Then a second accident occurred-Another little green man similarly fell from point A to point O, and died. The ratio of the times taken by the first green person to second green person to fall from A to O is
