Asatellite is in a circular orbit around the earth. the period of the satellite is 25.4 hr. calculate the radius of the orbit of the satellite. data: mass of the earth = 5.98 x 1024 kg.

The path of a satellite orbiting the earth causes it to pass directly over two tracking stations a and b, which are 51 miles apart. when the satellite is on one side of the two stations, the angles of elevation at a and b are measured to be 87 degrees and 84 degrees, respectively. (a) how far is the satellite from station a? (b) how high is the satellite above the ground?
