A spacecraft is in a circular orbit about the moon, 1.23 x 105 m above its surface. The speed of the spacecraft is 1850 m/s, and the radius of the moon is 1.74 x 10 m. If the moon were a smooth, reflective sphere, (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 same angular speed about the center of the moon.) (a) Number i Units (b) Number i Units
