The square root was a typo! I wasn't using it in my calculations. Figured it out I'm pretty sure. I wasn't adding the PE's. It should be the sum of the potential energy when crossing the moons orbit and the potential energy just before is reaches the Earth's surface (using radius of the earth)...

Homework Statement Q: "Two meteoroids are heading for earth. Their speeds as they cross the moons orbit are 1km/s. The first meteoroid is heading straight for earth, what is it's speed of impact?" Velocity = 1km/s Rearth = 6.37E6 m Dmoon = 3.84E8 m G = 6.673E-11 N*m^2/kg^2Homework Equations E...
