In a double-star system, two stars of mass 6.0 *10^30 kg eachrotate about the system's center of mass at a radius of 2.0 * 10^11m.
(a) What is their common angular speed?
(b) If a meteoroid passes through the system's center of massperpendicular to their orbital plane, what minimum speed must ithave at the center of mass if it is to escape to "infinity" fromthe two-star system?
