(a) What is the escape speed on a spherical asteroid whose radius is 700 km and whose gravitational acceleration at the surface is 4.5 m//s^2? (b) How far from the surface will a particle go if it leaves the asteroid's surface with a radial speed of 1000 m/s? (c) With what speed will an object hit the asteroid if it is dropped from 1000 km above the surface? |
