A flat (i.e., unbanked) curve on a highway has a radius of 220.0 [m] . A car travels around the curve at a speed of 25.0 [m/s] . What is the minimum coefficient of friction that will prevent sliding?
Added by Leslie D.
Step 1
This force can be calculated using the formula for centripetal force, which is F = mv^2/r, where m is the mass of the car, v is its speed, and r is the radius of the curve. Second, we know that the maximum force of static friction (the force that prevents the car Show more…

A flat (unbanked) curve on a highway has a radius of 220.0 m. A car rounds the curve at a speed of 25.0 m/s. (a) What is the minimum coefficient of friction that will prevent sliding? (b) 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?
