A satellite travels in an elliptical orbit around Earth. At perigee (point P) its distance from Earth’s center is rP, and at apogee (point A) its distance is rA with rA>rP. Which of the following correctly compares the satellite’s kinetic energies KP and KA at these two points?
a) KP=KA
b) KP>KA
c) KP<KA
d) The relationship cannot be determined without knowing the satellite’s mass.
