Will speeding automobile stop more quickly with the wheels locked or with the wheels braked just for the point of impeding skidding Why?

A speeding automobile will stop more quickly with the wheels braked just enough to avoid skidding rather than with the wheels locked. When the wheels are locked, the tires slide over the road surface, which reduces friction and increases stopping distance. In contrast, braking without locking the wheels allows for optimal tire grip on the road, maximizing friction and enabling a shorter stopping distance. Thus, maintaining some rotation of the wheels enhances control and reduces skidding.
