A satellite orbits the Earth as shown. Model the satellite as a particle, and assume that the center of the Earth can be chosen as the origin of an inertial frame of reference.
Figure P3.69
The minimum and maximum distances from the center of the Earth are Rp = 4.5 × 107 m and RA = 6.163 × 107 m, respectively, where the subscripts P and A stand for perigee (the point on the orbit closest to Earth) and apogee (the point on the orbit farthest from Earth), respectively. If the satellite’s speed at P is υP = 3.2×103 m/s, determine the satellite’s speed at A.
