When stopping a car on an icy or wet road... or a dry road, for that matter... is it better to push the brake pedal hard enough to lock the wheels and make them slide? Or to push gently so that the wheels continue to roll? What is the point behind "anti-lock disk brakes"? Which coefficient of friction u, or uk is relevant to which case? (hint: start by considering the forces on different points on the wheel in each case, and calculate the largest possible deceleration for both conditions)
