Needs Complete typed solution with 100 % accuracy.           

John has been hired to design an exciting carnival ride. Tiff, the carnival owner, has decided to create the world's greatest
Ferris wheel. Tiff isn't into math; she simply has a vision and has told John these constraints on her dream: (i) the wheel
should rotate counterclockwise with an angular speed of a = 13 RPM; (ii) the linear speed of a rider should be 200 mph; (iii)
the lowest point on the ride should be c = 4 feet above the level ground. The wheel starts turning when Tiff is at the
location P, which makes an angle with the horizontal, as pictured. It takes her 1.5 seconds to reach the top of the ride.
(Impose coordinates with units in feet.)

(a) Impose a coordinate system with the origin at the center of the wheel. Find the coordinates T(t) = (x(t), y(t))
of Tiff at time t seconds after she starts the ride. (Round values to three decimal places as needed.)
