I think I just answered the same question, but somehow the posting has disappeared.
the equation in that post was
v = √(64h)
so when h = 134
v = √(64*134) = √ 8576 = appr. 92.6

Reiny,
So the velocity at the bottom of a 134foot hill would be v= 92.607?
*Making a litle more sense to me now. Thank you for your input.
