Indiana State University Physics Question

Question Description

Need help with my Physics question – I’m studying for my class.

A banked circular highway curve is designed for traffic moving at 59 km/h. The radius of the curve is 217 m. Traffic is moving along the highway at 39 km/h 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 the road? (Assume the cars do not have negative lift.)
