Aferris wheel has a radius of 10 m, and the bottom of the wheel passes 1 m above the ground. if the ferris wheel makes one complete revolution every 18 s, find an equation that gives the height above the ground of a person on the ferris wheel as a function of time. (let y be the height above the ground in meters and let t be the time in seconds. assume that when t = 0 the person is 11 m above the ground and going up.)
y =11+9sin(π9t)
