6.29 At point A on its earth orbit, the radius, speed, and flight path angle of a satellite are ra = 12, 756km, VA = 6.5992 km/s, and YA = 20°. At point B, at which the true anomaly is 150°, an impulsive maneuver causes Av = +0.75820km/s and Av, = 0. (a) What is the time of flight from A to B? (b) What is the rotation of the apse line as a result of this maneuver? {Ans.: (a) 2.045 h; (b) 43.39° counterclockwise}
