A spacecraft is in a circular orbit about the moon 186

Question

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.)
