Meriam, Kraige & Bolton — Plane Kinematics of Rigid Bodies: Problem 5_160

5/160 A radar station $B$ situated at the equator observes a satellite $A$ in a circular equatorial orbit of 200-km altitude and moving from west to east. For the instant when the satellite is $30^\circ$ above the horizon, determine the difference between the velocity of the satellite relative to the radar station, as measured from a nonrotating frame of reference, and the velocity as measured relative to the reference frame of the radar system.
