The force needed to keep a car from skidding on a curve varies jointly as theweight of the car and the square of the car’s speed and inversely as the radiusof the curve. if 126 lb of force keeps a 1200 lb car driving at 25 mph fromskidding on a curve of radius 400 ft, what force would keep the same car going45 mph from skidding on a curve of radius 650 ft?
