A double Ferris wheel has a 50-foot bar attached to a main support at the center of the bar. The center is 40 feet off the ground. The bar revolves counterclockwise once every 60 seconds. Attached to each end of the bar is a wheel with a radius of 10 feet. If the main support bar were stationary, each of the two wheels would complete a counterclockwise revolution in 15 seconds. Assume that at time t = 0) a rider is at a point the farthest to the right as possible. 5. Write an equation to describe the rider's height y at time t. Hint: the height above the center is the sum of the heights of the two pink triangles. 6. Write an equation to describe the rider's horizontal position x at time t. As- sume that the x-position of the center of the bar is 0 feet. 7. What is an appropriate interval of t values that will capture an entire ride?
