i) Determine the escape speed on the spherical asteroid whose radius is around 520 km and whose gravitational acceleration at the surface is around 3.5 m/s2?
ii) Determine how far from the surface will a particle go when it leaves the surface of asteroid having a radial speed of around 1000 m/s?
iii) With what speed will an object strike the asteroid when it is dropped from 1000 km over the surface?
