The Pampanga Eye, in Sky Ranch Pampanga, is the tallest Ferris wheel in the Philippines. It has a diameter of 213 feet. When the Pampanga Eye is in uniform motion, it completes one revolution every 20 minutes, The height h, in feet above the ground, of a person riding on the Pampanga Eye can be estimated by h(t)=118-95 cos (π/10 t) where t is the time in minutes since the person started the ride. a. How high is the person at the start of the ride (t = 0)? b. How high is the person after 15 minutes?
