A spacecraft is in circular orbit about the moon, 1.22 x105m above its surface. The speed of the spacecraft is1620 m/s, and the radius of the moon is 1.74 x 106 m. Ifthe moon were a smooth reflective sphere, a) how far below themoon's surface would the image of the spacecraft appear, andb) what would be the apparent speed of the spacecraft's image?(Hint: Both the spacecraft and its image have the same angularspeed about the center of the moon.) I understand part a, but notpart b could someone please exlpain?
