Question

Skidding in a Curve: A car is traveling on a curve that forms
a circular arc. The force F needed to keep the car from skidding is jointly proportional to the weight w of the car and the square of its speed s and is inversely proportional to the radius r of the curve.

A car weighing 1600 lb. travels around a curve at 60 mi/h. The next car to round this curve weighs 2500 lb. and requires the same force as the first car to keep from skidding. How fast is the second car traveling?
