Question
There are stars that rotate extremely rapidly and are known as Neutron Stars. They are believed to have been formed from the inner core of a larger star that collapsed due to its own gravitation, to a star of very small radius and very high density. Before collapse, the core had radius R=7 x 105km, had a mass of 2.0 solar masses, and was rotating at 1.0 revolutions every 10.0 days. If it were to undergo gravitational collapse to a neutron star of radius 10.0km, what would its rotation speed be? (assume its a uniform sphere at all times)
Explanation / Answer
1 solar mass = 1.9891
