π /2 and y(t)=r sin( ω t - π /2 ), where r , ω can be determined from the information given. Provide answers below accurate to 3 decimal places. (Note: We have imposed a coordinate system so that the center of the ferris wheel is the origin. There are other ways to impose coordinates, leading to different parametric equations.) ) (a) r = 100 100 feet (b) ω = 0.235 0.235 rad/sec (c) During the first revolution of the wheel, find the times when the rider's height above the ground is 80 feet.
