(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

2 meteoroids are 160,000 km from Earth's center and heading straight toward Earth. One is moving at 10 km/s, the other at 20 km/s. At what speeds will they strike Earth?

2. Relevant equations

K + U = K_i + U_i

U = -GMm/R

3. The attempt at a solution

Ok, either i'm having a serious brain fart. But are those the right equations i'm concentrating on?
