4) A point mass of 5 kg is placed at x = +6 m, y = 0 m, a point mass of 4 kg is placed at x = -6 m, y = 0 m, a point mass of 3 kg is placed at x = 0 m, y = -2 m, and a point mass of 3 kg is placed at x = +6 m, y = +2 m. The masses are spinning about the line y = x (45 degrees with the origin) and their rotational KE about that line is 641 J. How fast are they spinning about this line in rad/s?
