###### Question details

A curved highway has only one lane with a centerline radius of
800 ft. A building is located

25 ft. from the centerline. The road is level. Take the coefficient
of braking friction as 0.36

and perception-reaction time as 2.5 seconds.

a. Determine the appropriate speed limit on the curve to ensure
stopping sight distance;

b. Determine the rate of super-elevation (assume the coefficient of
side friction equals

0.15)
