A ferris wheel with a radius of 30 feet has its center 33 feet above the ground. When in operation, it makes a full turn every 15 seconds. Let H(t) be the height of a point P on the ferris wheel t seconds after it begins operation, and suppose you know that Preaches the higihest point at t = 26 seconds. The maximum height is feet. The first time P was at this height was a t = seconds. The next time P will be at this height will be att seconds. We can model H(t) using a cosine function with amplitude A = and phase shift (enter the least possible value of the phase shift)
