3. Alpha Centauri A and B are Sun-like stars, and together they form the binary star Alpha Centauri AB. Alpha Centauri A has 1.1 times the mass of the Sun while Alpha Centauri B has 0.907 times the Sun’s mass. (Sun’s mass is 1.989 x 1030 kg.) The pair orbit about a common center with an orbital period of 79.91 years. Their elliptical orbit is eccentric, so that the distance between A and B varies, but if we assume it is circular, we can calculate the average velocities. Find the average velocities of the two stars.
