A satellite is put into an elliptical orbit around the Earth. When the satellite is at its perigee, its nearest point to the Earth, its height above the ground is
h
p
=
215.0
km,
and it is moving with a speed of
v
p
=
8.450
km/s.
The gravitational constant
G
equals
6.67
Γ

kg.
When the satellite reaches its apogee, at its farthest point from the Earth, what is its height
h
a
above the ground?
For this problem, choose gravitational potential energy of the satellite to be
0
at an infinite distance from Earth.
