12-16. Estimate the maximum rotation rate of a strengthless asteroid (held together by gravity alone) by setting the rotation speed at the equator equal to the escape velocity. (a) Approximate the asteroid by a spherical body. (Hint: Your answer should depend only on the density of the body, not its size.)
