At a county fair, a boy takes his teddy bear on the giant Ferris wheel. Unfortunately, at the top of the ride, he accidentally drops his stuffed buddy. The wheel has a diameter of 16.7 m, the bottom of the wheel is 3.55 m above the ground and its rim is moving at a speed of 1.59 m/s. How far from the base of the Ferris wheel will the teddy bear land?
