an earth satellite in an elliptical orbit moves with



a) faster speed as it age
b) none of the above
c) constant speed
d) slower speed as it age

Second, since this is not my area of expertise, I searched Google under the key words "satellite orbit speed" to get this:

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.
