- (a) What is the escape speed on a spherical asteroid whose radius is 502 km and whose gravitational acceleration at the surface is 0.870 m/s? (b) How far from the surface will a particle go if it leaves the asteroid's surface with a radial speed of 647 m/s? (c) With what speed will an object hit the asteroid if it is dropped from 665.5 km above the surface? (a) Number i Units (b) Number Units (c) Number UnitsAround 2.5 centuries ago, several physicists of the time came up with the notion of a dark star. This was a star so dense, with so much gravity, that not even light could escape. The calculations used Newtonian mechanics. In class, we calculated the escape speed from the surface of the earth or the distance from the sun, and the mass of the planet or star. Here, the process is partially reversed. Calculate the dark star radius from the mass of the star and the escape speed.
