Two stars are at rest 1.0×1014m apart. This is about 10 times the diameter of the solar system. The first star is the size of our sun, with a mass of 2.0×1030kg and a radius of 7.0×108m . The second star has mass 9.0×1030kg and radius of 1.19×109m . Gravitational forces pull the two stars together. What is the speed of each star at the moment of impact?
