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 ρA = 93 m, while path B-B uses the width of the road to good advantage in increasing the radius of curvature to ρB = 165 m. If the drivers limit their speeds in their curves so that the lateral acceleration does not exceed 0.86g, determine the maximum speed for each path.

Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.
