Q. 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.

(1) what is the minimum coefficient of friction that will prevent sliding?

(2) Suppose the highway is icy and the coefficient of friction between the tires and pavement is only one-third what you found in part (1). What should be the maximum speed of the car so it can round the curve safely?
