The center-line of the inside lane of a roadway is on a horizontal curve with a 6o54'29" degree of curvature. The central angle of the curve is 40o. There are 6-foot-high snow banks 15 feet from the center-line of the inside lane. The inside lane has no grade and has a posted speed limit of 55 mph. Assume a vehicle is traveling at the posted speed and that the perception-reaction time for the driver is 1.5 seconds. Each question is worth 2 points. How long (time) does it take a vehicle to stop from the time the brakes are applied? Enter your answer accurate to 3 significant figures.
