The velocity v of a roller coaster in feet per second at the bottom of a hill is Where h is the height of the hill in feet.
Simplify the equation.
Determine the velocity of a roller coaster at the bottom of a 134-foot hill.
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
So the velocity at the bottom of a 134-foot hill would be v= 92.607?
*Making a litle more sense to me now. Thank you for your input.
