Question

A special 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?

Please help me!

Explanation / Answer

given that radius of circular loop = r = 24m weight = 990N W = mg    m = W/g = 990N/9.8= 101kg at the top normal force = N = 360N at top the loop N + mg = mv2/r v = (360N+990N)24/101 v = 17.9m/s
