A driver traveling at 50mph sees a wall at a certain distance ahead. The driver applies the brakes immediately (perception time is 3 seconds) and begins slowing the vehicle at 6m/sec2 (decelerating). If the distance from the stopping point to the wall is 12m., how far was the car from the wall upon perception?

(TRAFFIC AND HIGHWAY ENGINEERING) A tall building is located 13.5 m from the centerline of the right lane of a local road and 19.5 m from the centerline of the right lane of an intersecting road in figure below. If the maximum speed limit on the intersecting road is 56 km/h, what should the speed limit on the local road be such that the minimum sight distance is provided to allow the drivers of approaching vehicles to avoid imminent collision by adjusting their speeds? Approach grades are 2 percent.
