Chapter 13, Problem 39P

To determine

To Find:

a) The escape speed on a spherical asteroid whose radius is $500km$ and whose gravitational acceleration at the surface is $3.0m/s^2$

b) The distance from the surface that the particle will go if it leaves the asteroid’s surface with a radial speed of $100 m/s$

c) The speed with which an object will hit the asteroid if it is dropped from $1000 km$ above the surface
