AP Physics QuestionAn amusement park ride consists of a large vertical wheel of radius that rotates counterclockwise on a horizontalaxis through its center, as shown above. The cars on the wheel move at a constant speed . Points andrepresent the position of a car at the highest and lowest point of the ride, respectively. A person of weight sitsupright on a seat in one of the cars. As the seat passes point , the seat exerts a normal force with magnitudeon the person. While passing point , the person releases a small rock of mass , which falls to the groundwithout hitting anything.2.
