Question
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 1014 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 9.0×105 km (comparable to our sun); its final radius is 17 km.
If the original star rotated once in 30 days, find the angular speed of the neutron star.

The density of a neutron star is roughly 1014 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 9.0105 km (comparable to our sun); its final radius is 17 km. If the original star rotated once in 30 days, find the angular speed of the neutron star. omega 2 = ?Explanation / Answer
( 2p / (30 * 86400) ) * ( 9.0 x 105 /17km)2 = 86400 came from seconds / day and everything else was given
