Stephan, a student in a physics class makes the following statement: All the dots are moving at the same rotational speed. Each dot completes one rotation in the same amount of time. Aaleyah says: The dots closer to the rim travel farther for each rotation, so they are moving at greater tangential speed. Which student is correct

Aspecial electronic sensor is embedded in the seat of a car that takes riders around a circular loop-the-loop ride at an amusement park. the sensor measures the magnitude of the normal force that the seat exerts on a rider. the loop-the-loop ride is in the vertical plane and its radius is 23 m. sitting on the seat before the ride starts, a rider is level and stationary, and the electronic sensor reads 740 n. at the top of the loop, the rider is upside down and moving, and the sensor reads 370 n. what is the speed of the rider at the top of the loop?
