Consider an asteroid with a radius of 17 km and a mass of 3.8×1015 kg. Assume the asteroid is roughly spherical. What is the acceleration due to gravity on the surface of the asteroid? Suppose the asteroid spins about an axis through its center, like the Earth, with a rotational period T . What is the smallest value T can have before loose rocks on the asteroid's equator begin to fly off the surface? (Answer: T = # h)
