If it were to undergo gravitational collapse to a neutron star of radius 11 km, losing three-quarters of its mass in the process, what would its rotation speed be? Assume that the star is a uniform sphere at all times, andfs8n gqd5u pk rr*4:v; that the lost mass carries off no angular momentum. $\times10^{9 }$ $rev/day$
