Question 850593
The demon drop ride at Cedar Point takes riders to the top of a tower and drops them  60 feet at speeds reaching 80 feet per second. A function that models this ride is h=-16t^2+64t-60  where h is the height in feet and t is the time in seconds About how many seconds does it take for riders to drop from 60 feet to 0 feet?
===============
I don't think h=-16t^2+64t-60 is correct
h(0) = -60 feet
---------------
h=-16t^2+64t-60 = 0
-4t^2 + 16t - 15 = 0
