##### Reference no: EM13544785

(a) What is the escape speed on a spherical asteroid whose radius is 510 km and whose gravitational acceleration at the surface is 3.3 m/s2?

(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?
