You can put this solution on YOUR website! A ferris wheel is 40 meters in diameter and boarded at ground level. The wheel makes one full rotation every 8 minutes, and at time you are at the 9 o'clock position and descending. Let denote your height (in meters) above ground at minutes. Find a formula for
--------------
At the 9 o'clock position you're at the level of the center, = 20 meters high.
-------------
Formula for height?
h(t) = 20 + 20sin(t*pi/4 - pi/2)
h in meters, t in minutes, t = 0 at ground level, angles in radians
