A spacecraft is in a circular orbit about the moon, 1.86 x105 m above its surface. The speed of the spacecraft is1460 m/s, and the radius of the moon is 1.74 x 106 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 about the center of the moon.)
