A ferris wheel with a radius of 20 feet has its center 28 feet above the ground. When in operation, it makes afull turn every 25 seconds.Let H(t) be the height of a point P on the ferris wheel t seconds after it begins operation, and suppose youknow that P reaches the higihest point at t = 33 seconds.The maximum height isThe first time P was at this height was a t =The next time P will be at this height will be at t =ofeet.We can model H(t) using a cosine function with amplitude A =phase shift0 seconds.seconds.O and(enter the least possible value of the phase shift)
