An airplane in level flight at an altitude h and a uniform speed v passes directly over a radar tracking station A. Using the equations of this chapter (rather than polar coordinates), attach the inertial frame of reference to the ground and suppose anon-rotating earth. Attach the moving frame to the antenna, with the x axis pointing always from the antenna towards the airplane. Compute: a) the relative velocity v rel and the angular velocity (? &) of the radar antenna b) the relative acceleration a rel and the angular acceleration (?&& ) of the radar antenna
