A spherical mirror is polished on both sides. When concave side is used as a mirror, the magnification is +2.0.

Or else, enter a positive number.

Question2

A spacecraft is in a circular orbit about the moon, 1.65 x 105 m above its surface. The speed of spacecraft is 1530 m/s, and the radius of the moon is 1.74 x 106 m. If the moon were a smooth, reflective sphere.

(a) How far under the moon's surface would the image of the spacecraft appear, and

(b) What would be apparent speed of the spacecraft's image?
