Best ResponseYou've already chosen the best response.0Suppose a star the size of our Sun, but with mass 4.0 times as great, were rotating at a speed of 1.0 revolution every 5.0 days. If it were to undergo gravitational collapse to a neutron star of radius 15km , losing threequarters of its mass in the process, what would its rotation speed be? Assume that the star is a uniform sphere at all times, and that the lost mass carries off no angular momentum
