In a loop-the-loop ride a car goes around a vertical, circular loop at a constant speed. The car has a mass m = 279 kg and moves with speed v = 17.34 m/s. The loop-the-loop has a radius of R = 11.4 m.1)
What is the magnitude of the normal force on the care when it is at the bottom of the circle? (But as the car is accelerating upward.)
