Suppose a star the sizvhi1xz)re7yfs abw2 2;vi3 y5 e of our Sun, bpss*whf- n5soq0g9 7j ut with 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 staosgqhf0 7w-j5*s9 npsr 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, and that the lost mass carries off no angular momentum. $\times10^{9 }$ $rev/day$
