Our sun rotates around its axis once every 27 days. • What is the sun's angular velocity in rad/s? • What is the sun's moment of inertia in kg*m? (Assume it's a solid sphere) If the sun turned into a red giant, the radius would increase to 100 times its current radius. Assuming no loss of mass and that the sun is a solid sphere, what would be the sun's new moment of inertia? • What would be the sun's new angular velocity assuming angular momentum is conserved? msun = 1.99 * 1030kg Tsun = 6.96 * 105 km
