Aspecial electronic sensor is embedded in the seat of a car thattakes riders around a circular loop-the-loop at an amusement park. the sensor measures the magnitude of the normal force that the seatexerts on a rider. the loop-the-loop ride is in the vertical planeand its radius is 24 m. sitting on the seat before the ride starts, a rider is level and stationary, and the electronic sensor reads990 n. at the top of the loop, the rider is upside-down and moving, and the sensor reads 360 n. what is the speed of the rider at thetop of the loop?
