a) The fastest possible rate of rotation of a planet is that for which the gravitational force on material at the equator barely provides the centripetal force needed for the rotation. For a planet with a uniform density of 6.6 g/cm3, typical of many planets and asteroids, evaluate the shortest period of rotation.

b) Certain neutron stars (extremely dense stars) are be- lieved to be rotating at about 1.1 rev/s. If such a star has a radius of 18.9 km, what must be its minimum mass so that ob- jects on its surface will be attracted to the star and not thrown off by the rapid rotation?
