A high-speed railway car goes around a flat, horizontal circle of radius 470 m at a constant speed. The magnitudes of the horizontal and vertical components of the force of the car on a 51.0 kg passenger are 210 N and 500 N, respectively. (a)What is the magnitude of the net force (of all the forces) on the passenger? (b) What is the speed of the car?
