A spacecraft is in a circular orbit regarding the moon, 1.76x105 m above its surface. The speed of the spacecraft is1800 m/s, and the radius of the moon is 1.74x106 m. If the moon were a smooth, reflective surface, (a) how far below the moon's surface would the image of the spacecraft appear, and (b) what would be the apparent speed of the spacecraft's image? (Hint: both the spacecraft and its image have the similar angular speed regarding the center of the moon.)
