  • How do you solve this Physics Problem dealing with friction on banked curves?

    Problem: A banked curve is designed for traffic moving at 15.3 m/s. The radius of the curve is 220m. Traffic is moving along the curve at 10.6 m/s on a rainy day. What is the minimum coefficient of friction between tires and road that will allow cars to take the turn without sliding off? My approach: I first determined the banking angle at 10.6 m/s, which I found out to be 6.2 degrees. I then resolved the frictional force into its x-component and then used that as below: m*v^2/R = FN sin A - mu...
