Question: Two meteoroids are heading for earth. Their speeds as they cross the moon's orbit are 2.0 km/s. . The first meteoroid is heading straight for earth. What is its speed of impact? . The second misses the earth by 5000 km. What is its speed at its closest point? Using similar agrument, E at moon's orbit = (1/2)mv2 - GMm/R = E atthe closest point = (1/2)mv22 -GMm/(r1+r)
