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 1014times 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 6.0×105km (comparable to our sun); its final radius is 17 km . Part A If the original star rotated once in 32 days, find the angular speed of the neutron star.

Explanation / Answer

apply the law of conservatio n of Angular momentum as I1W1 = I2W2


here

(6e 8* 6e 8) * (2pi/(32*24*60*60)) = (17e 3)^2* w

or w = 1415.43 rad/s
