The energy of the meteorite would be:v velocitym mass of meteoroidM mass of earthG gravitational constantR of the distance between the meteorite and earthThe total energy must remain constant. Let R the distance of the earth to the moon and r is the radius of the earth, we obtain:v₁ = 1 km/sSolve for v₂.
