Two stars are at rest 1.0×10^14m 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 2.0×10^30kg and a radius of 7.0×10^8m . The second star has mass 7.3×10^30kg and radius of 1.15×10^9m . Gravitational forces pull the two stars together. What is the speed of each star at the moment of impact?
