Under some circumstances, a star can collapse into an extremely dense object made mostly of neutrons and called a neutron star. The density of a neutron star is roughly 10^14 times as great as that of ordinary solid matter. Suppose we represent the star as a uniform, solid, rigid sphere, both before and after the collapse. The star’s initial radius was 657,694 km (comparable to our sun); its final radius is 13 km. If the original star rotated once in 22 days, find the angular speed of the neutron star. Hint: there are 86,400 s in a day
