7. Satellites that are used for TV must remain over the same point on the Earth's surface at all times, so that the antenna is always pointed at the satellite. This is known as the geostationary orbit, and requires a height of 35900 km above the Earth's surface. a) Find the angular velocity, in radians/hour, required for the satellite to remain over the same point on Earth. b) What distance would the satellite have traveled after 72 hours? (The Earth's radius is 6400 km)
