Suppose a star has a mass three times that of our sun (that is, the star's mass will be 6 x 1030 kg) and starts out as a sphere with an initial radius several times larger than our sun (3.48 x10º m). It is initially spinning with one revolution every 12 days. What is its angular momentum, in kg m2/s?
