A driver travelling at 50mph sees a hazard (boulder) at a certain distance ahead. The driver then applies the brakes immediately (PIEV) time is 2 seconds and begins slowing the vehicle at 10m/sec? (decelerating). If the distance from the stopping point to avoid hitting the boulder is 10.28m, how far was the car from the boulder upon perception?

Problem 4 Two cars are approaching each other from the opposite direction. Both cars are traveling the same grade of 4%. The speed of the car ruhning uphill is 40mph and the other running at 60mph. If reaction time for both drivers is 3.5 sec and friction is 0.5, compute the maximum distance required to avoid collision.
Calculate the passing sight distance on a two lane road having the design speed of 86 kmph and reaction time 2 sec. Assume one way traffic. Take acceleration of overtaking and overtaken vehicle as 3 m/s2 and 1.5 m/s2 respectively. Assume that overtaken vehicle starts accelerating after the reaction time of overtaking vehicle. Take space headway as 18 m.
1. A car is approachin an intersection with velocity 35 mph. When the car is at a distance of 200 ft from the intersection, the signal turned yellow. If the driver decides to break, will he be able to stop safely? The driver's reaction time is 1.5 s. Assume the road surface as leveled. The maximum braking effort is applied. Will your answer change, if the grade of the road surface is downhill 3%? A car is at a distance of 200 ft from an intersection stop line when the signal turned yellow. What should be the minimum speed of the car (miles/hour) if the driver decides to apply brake and is just able to stop at the line? Use reaction time of 1.5 s and the road surface has zero grade.
