Joe,
I found a graph here
http://www.hq.nasa.gov/pao/History/conghand/possibil.htm
that shows speed versus altitude (in obscure units, but never mind) for both sounding rockets and orbital satellite launches (into a circular orbit)
It's not in the greatest detail.
Now to find the same data for the way down.
