To determine

To show: The equation relating $v_H$ and $v_V$ (in mi/h) is that of a circle. when A communications satellite remains stationary at an altitude of 22,500 mi over a point on Earth’s equator. It therefore rotates once each day about Earth’s center. Its velocity is constant, but the horizontal and vertical components, $v_H$ and $v_V$, of the velocity constantly change. The radius of earth is 3960 mi.
