The figure shows two possible paths for negotiating an unbanked turn on a horizontal portion of a race course. Path A-A follows the centerline of the road and has a radius of curvature PA = 81 m, while path B-B uses the width of the road to good advantage in increasing the radius of curvature to pg = 189 m. If the drivers limit their speeds in their curves so that the lateral acceleration does not exceed 0.68g, determine the maximum speed for each path. 189 m Answers: (VA)max = (VB)max = i tel Α Β\ 81 m m/s m/s
