The figure shows two possible paths for negotiating an unbanked turn on a horizontal portion of a race course. Path A-A follows thecenterline of the road and has a radius of curvature Pa = 88 m, while path B-B uses the width of the road to good advantage inincreasing the radius of curvature to pB = 183 m. If the drivers limit their speeds in their curves so that the lateral acceleration does notexceed 0.84g, determine the maximum speed for each path.A B183 m88 mAnswers:(valmax =im/s(VB) max =im/s
