suppose a star the size of our sun, but with mass 9.0 times as great, were rotating at a speed of 1.0 revolution every 7.0 days. if it were to undergo gravitational collapse to a neutron star of radius 14 kmkm , losing three-quarters of its mass in the process, what would its rotation speed be? assume also that the thrown- off mass carries off either
