    Use conservation of energy. The potential energy, denoted as W(r) is:

    W(r) = -G M m/r,

    where M is the mass of the Earth, m is the mass of the ...

    Solution Summary

    Using conservation of energy we calculate the speed of meteoroids when they are at 5000 km from Earth using the given initial speed when they cross the Moon's orbit.
