The geocentric satellite a€?Apple' was first launched into an elliptic orbit with the perigee (nearest point) of rp = 6570 km and apogee (farthest point) at rA = 42,250 km. The respective velocities were vp = 10.25 km/s and vA = 1.594 km/s. Show that the above data are consistent with the conservation of angular momentum of the satellite about the centre of the earth. |
