Suppose the highway is icy and the coefficient of friction, Ask an Expert

Academics

A flat (unbanked) curve on a highway has a radius of 240.0m . A car rounds the curve at a speed of 23.0 m. What is the minimum coefficient of friction that will prevent sliding?

Suppose the highway is icy and the coefficient of friction between the tires and pavement is only one-third what you found in part A. What should be the maximum speed of the car so it can round the curve safely?
