AP Physics B: Centripetal Force and Gravity

  1. 1. The problem statement, all variables and given/known data
    Two stars of mass m1 and m2 are in orbit around their center of mass. If 2m1=5m2, and thier orbital period is 120Ms, calculate the mass of the larger star, given that the distance between their centers is 1400Gm.

    2. Relevant equations

    3. The attempt at a solution
    I don't even know what to put as mass of the centripod, i kneed serious help

    What have you learnt about two-body problems? Reduced mass? Kepler's Laws?
