URGENT: Suppose that you are riding a Ferris wheel which rotate at any constant speed you wish. The chairs swivel so you are always sitting upright. Please explain why it is possible for you to feel weightless at only one spot on the Ferris wheel. What spot is this? Here, “weightless” is defined to mean that the normal force of contact from the chair on you (the rider) is zero.
