Neutron stars represent the final stage of life for some massive stars. Typically, they have radii of 10 km. Determine the magnitude of the centripetal acceleration for a piece of neutron star matter on the star surface at the equator (so the matter moves in a circle of radius 10km). Assume the neutron star rotates once every .003 seconds. This is what I did. a = w^2 * r a = (2pi/.003)^2 * (10) a = 4.38 x 10^7 m/s^2 The answer key tells me that the acceleration is 4.37 x 10^10 m/s^2. Where did I go wrong?
