Question 1188383: The force (f) needed to keep a car from skidding on a curve varies jointly as the weight of the car (w) and the square of its speed (s) Nad inversely as the radius of the curve (r). It takes 2800 pounds of force to keep an 1800 pound car from skidding on a curve with a radius of 425 feet at 45 mph. What force is needed to keep the same car from skidding when it takes a similar curve with a radius of 450 feet at 55 mph? Round to the nearest 10 pounds.
