Aroad engineer designs exit ramp of the ac expressway with a banked curve to allow a car to travel on the ramp with a speed of 40 mph when the ramp is ice covered and the coefficient of friction is zero. the curve has a radius of 35.0 meters.
a.) at what angle is the curve banked?
b.) if the coefficient of friction is normally 0.2, what is the maximum speed a car can negotiate the curve?
c.) if the coefficient of friction is normally 0.2, what is the minimum speed a car can negotiate the curve?
