What is the escape speed on a spherical asteroid whose radius is 387 km and whose gravitational acceleration at the surface is 0.595 m/s2? (b) How far from the surface will a particle go if it leaves the asteroid's surface with a radial speed of 568 m/s? (c) With what speed will an object hit the asteroid if it is dropped from 2376 km above the surface?

Consider a spherical asteroid with a radius of 20 km and a mass of 9.25 ✕ 1015 kg. Assume the asteroid is roughly spherical. (a) What is the acceleration due to gravity on the surface of this asteroid? m/s2 (b) 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? h
A spherical asteroid with a radius of 11 km approaches Earth with a speed 0.3c. What is the volume of the asteroid as determined by an Earth-based observatory. (The volume of an ellipsoid with semi-axis a,b, and d is 4π*a*b*d/3).

*Problem 6.66 You stand on a spherical asteroid of uniform density whose mass is 2.5 x 1016 kg and whose radius is 11 km (11 x 103 m). These are typical values for small asteroids, although some asteroids have been found to have much lower average density and are thought to be loose agglomerations of shattered rocks. You want to figure out how fast you have to throw the rock so that it never comes back...
Please show work, thanks!
