Explanation:
Essentially, Kinetic energy of the particle must equal the combined potential energies of earth and the moon when the object is on the moon's surface, meaning the full equation is
<h3>=Mass of Earth=
=Mass of Moon=
=distance from earth's center to the moon's=
=radius of moon=
After some algebra, the equation simplifies to
Plugging in the values of G, which is , should yield the proper answer of 2780m/s.
