Unformatted text preview: s to a final rate o f3.0 rev/s. If her initial moment of inertia was 4.6 kg m 2 , what is her final moment of inertia? 4. Suppose a star the size of our Sun, but with a mass 8.0 times as great, were rotating at a speed of 1.0 revolution every 12 days. If it were to undergo gravitational collapse to a neutron star of radius 11 km, losing threequarters of its mass in the process, what would its rotation speed by? Assume that the star is a uniform sphere at all times, and that the lost mass carries off no angular momentum....
