Traveling at a speed of \( 22 \) \( \text{m/s} \), the driver of an automobile suddenly locks the wheels by slamming on the brakes. The coefficient of friction between the tires and the road is \( 0.68 \). How much time does it take for the car to come to a halt? As usual, ignore the effects of air resistance and anything else that could interfere with this problem.
