A stellar black hole may form when a massive star dies. The star collapses down to a single point. Our Sun will not become a black hole because it does not have enough mass, so let us imagine a black hole with eight times the mass of the Sun. A single point has no radius, but a black hole has an effective radius known as the Schwarzscfhild radius. If an object gets inside the Schwarzscfhild radius, it never escapes. The Schwarzscfhild radius of an eight solar-mass black hole is about 24 km.

a. Find the escape speed using the Schwarzscfhild radius.

b. Compare your answer to the speed of light and speculate on how these objects got the name ''black hole.''
