Question

A flat (unbanked) curve on a highway has a radius of 225.0 m. A car rounds the curve at a speed of 24.0 m/s. a. What is the minimum coefficient of static friction that will prevent sliding? b. Suppose that the highway is icy and the coefficient of friction between the tires and pavement is only one-third what you found in the previous part. What should be the maximum speed of the car so it can round the curve safely?

Step 1

We need to find the minimum coefficient of static friction that will prevent a car from sliding on a flat curve with a radius of 225.0 m when the car is moving at a speed of 24.0 m/s. Then, if the coefficient of friction is reduced to one-third of its original Show more…
