SUMMARY
The safest speed for a vehicle navigating a banked curve with a radius of curvature of 120 meters and a banking angle of 3.5° on an icy road is determined by the absence of friction. The relevant equation for this scenario is m(v²/r), where 'm' is mass, 'v' is velocity, and 'r' is the radius. Since the road is icy, the static friction coefficient is effectively zero, necessitating a calculation based solely on the banking angle and radius. For precise calculations, refer to the resources provided, such as HyperPhysics.
