Show that the effect of the radius of revolution being a little different from the length of the string exactly cancels the effect of the tension (equivalently the washer weight) being a little different from centripetal force, so that the period can be expressed in terms of just the masses and length of string (without referencing the angle).

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?
