Q. Fairgoers ride a Ferris wheel with a radius of 5. The wheel completes one revolution every 33.
a) What is the average speed of a rider on this Ferris wheel?
b) If a rider accidentally drops a stuffed animal at the top of the wheel, where does it land relative to the base of the ride? (Note: The bottom of the wheel is 1.75 above the ground.)
