The sun has a rotation period (about an axis through its center) of about 25 days, rather than the one day for our earth. In about 5 billion years, the sun will become a red giant star and its radius will expand to about the orbit of the earth. Determine the new rotational period of the sun once it becomes a red giant. Hint If your system is the sun, then there are no external torques acting on the system during this process. Also, assume the sun (and the red giant) to be solid spheres.
