While at the county fair, you decide to ride the ferris wheel. having eaten too many candy apples and elephant ears, you find the motion somewhat unpleasant. to take your mind off your stomach, you wonder about the motion of the ride. you estimate the radius of the big wheel to be 15 m, and you use your watch to find that each loop around takes 25 s. what are your speed and magnitude of your acceleration? what is the ratio of your apparent weight to your true weight at the top of the ride? what is the ratio of your apparent weight to your true weight at the bottom?
