A banked circular highway curve is designed for traffice moving at 65km/h. The radius of the curve is 200 m. Traffic is moving along the highway at 40 km/h on 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.)

At what should a highway be banked for cars travelling at a speed of 100 km/h if the radius of the road is 400 m and no frictional forces are involved?
