Aboy throws a pebble into the center of the pond. a floating leaf near the waters edge oscillates ( moves up and down ) two complete cycles in one second as water waves move past the leaf. the waters wavelength is 10 meters. what is the waves velocity?

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?
