This statement implies that the masses of the two stars are equal (see figure below). Assumethe orbital speed of each star is v| = 225 km/s and the orbital period of each is 11.6 days. Find the mass Mof each star. (For comparison, the mass of our Sun is 1.99 x 1030 kg.)MXCMMPart 1 of 3 - ConceptualizeFrom the given data, it is difficult to estimate a reasonable answer to this problem without working throughthe details and actually solving it. A reasonable guess might be that each star has a mass equal to or slightlylarger than our Sun because fourteen days is short compared to the periods of all the Sun's planets.Part 2 of 3 - CategorizeThe only force acting on each star is the central gravitational force of attraction which results in a centripetalacceleration. When we solve Newton's second law, we can find the unknown mass in terms of the variablesgiven in the problem.
