A ferris wheel is 30 meters in diameter and boarded from a platform that is 5 meters above the ground. The six o'clock position on the ferris wheel is level with the loading platform. The wheel completes 1 full revolution in 2 minutes. The function \( h=f(t) \) gives your height in meters above the ground \( t \) minutes after the wheel begins to turn. What is the amplitude? What is the equation of the Midline? What is the period? The equation that models the height of the ferris wheel after \( t \) minutes is: \( f(t)= \) How high are you off of the ground after 1 minutes? Round your answer to the nearest meter.
