Two stars m1 and m2 of equal mass make up a binary star system. they move in a circular orbit that has its center at the midpoint of the line that separates them. if m1-m2-6.95 sm (solar mass), and the orbital period of each star is 2.20 days, find their orbital speed. (the mass of the sun is 1.99x 1030 kg.) km/s m2
