The force needed to keep a car from skidding on a curve varies inversely as the radius of the curve and jointly as the weight of the car and the square of the speed. if 303 lb of force keeps a 2500-lb car from skidding on a curve of radius of 500 ft at 30 mph, what force (to the nearest tenth of a pound) would keep the same car from skidding on a curve of radius of 650 ft at 50 mph?
