The speed limit on the main road through town is currently 55 mph. But a concern was raised at a city council meeting, that this speed is too high for safety at a particular intersection. Due to curves in the road, drivers approaching that intersection are first able to see the stop sign from 44 meters away. The key question is, does that give them enough advance warning to stop before reaching the intersection, if they are going 55 mph? What is the braking distance (how much distance a car travels from the time the brakes are applied, until the car comes to a complete stop). Compute the worst-case stopping distance (number of meters) at this intersection for a vehicle going 55 mph.
