The Demon Drop at Cedar Point in Ohio takes riders to the top of a tower and drops them. A function that approximates this ride is h = -16t2 + 64t + 60 where h is the height in feet and t is the time in seconds. What is the initial height of the ride before they are dropped? How long does it take for the riders to reach ground level? How high are the riders after 3 seconds? What is the maximum height?
