Plaskett's binary system consists of two stars that revolve in a circular orbit about a center of mass midway between them. this statement implies that the masses of the two stars are equal (see figure below). assume the orbital speed of each star is |v with arrow| = 160 km/s and the orbital period of each is 13.7 days. find the mass m of each star. (for comparison, the mass of our sun is 1.99 1030 kg.)
