Question 402921
"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" ___ f = k * w * s^2 / r^2


use the given conditions to find k ___ k = (f * r^2) / (w * s^2) = (242 * 500^2) / (2000 * 30^2)


use the calculated value of k to find the new force
