## Surveillance Satellite...Part B

A suveillance satellite circles Earth at a height of h miles above the surface. Suppose that d is the distance, in miles, on the surface of Earth that can be observed from the satellite.

(a) If d is to be 2500 miles, how high must the satelite orbit above Earth?

(b) If the satellite orbits at a height of 300 miles, what distance d on the surface can be observed?

NOTE: radius of Earth is given to be 3960 miles.
