The force needed to keep a car from skidding on a curve varies jointly as the weight of the car
and the square of the speed, and inversely as the radius of the curve. It takes 3800 pounds of
force to keep an 1800 pound car from skidding on a curve with radius 425 feet at a speed of 45
mph. What force is needed to keep the same car from skidding when it takes a similar curve with
radius 450 feet at 55 mph?
