Solved in 3 steps
- The driver of a car travelling at a certain speed suddenly sees an obstruction ahead and travelled a distance of 55.8 m during the perception time of 1.45 sec. Determine the car's speed of approach in kph.Compute the minimum passing sight distance forthe following data. Speed of passing car – 90kph Speed of overtaken vehicle – 80 kph Time of initial maneuver – 4 sec Ave. acceleration – 2.4 kph/sec2 Time passing vehicle occupies left lane – 9 sec Distance between passing vehicle at the end of its maneuver and opposing vehicle – 80 mA driver driving at 69 kph at a straight flat portion of the highway suddenly encounters an obstruction. He applies his brakes. If the coefficient of friction of the roadway to the tires is equal to 0.5, calculate the maximum safe distance (rounded to the nearest meters) the driver can apply his brakes to avoid collision. g = 9.81 m/s^2

Assuming the following car to have a perceptionreaction time of 2s, what must be the minimum following distance in order to avoidcollision?Determine the required total passing sight distance for the following: Speed of the passing car = 100 kph; Speed of the overtaken vehicle = 80 kph; Time of initial maneuvers = 5 sec; Time passing vehicle occupies left lane = 10 secs; Distance between the passing car and opposing car at the end of maneuver = 20 m; Average acceleration = 2.5 kph/sec. a. 502.75 m b. 602.75 m c. 702.75 m d. 402.75 mCOMPUTE THE MINUMUM PASSING SIGHT DISTANCE FOR THE FOLLOWING DATA: SPEED OF THE PASSING CAR = 90 KPH SPEED OF THE OVERTAKEN VEHICLE = 80 KPH TIME OF INITIAL MANEUVER = 4 SEC AVERAGE ACCELERATION = 2.4 KPH/SEC TIME PASSING VEHICLE OCCUPIES THE LEFT LANE = 9 SEC DISTANCE BETWEEN THE PASSING VEHICLE AT THE END OF ITS MENEUVER AND THE OPPOSING VEHICLE = 80 KPH
- Sight Distance A driver is traveling at 55 mi/h on a wet road. An object is spotted on the road 450 ft ahead and the driver is able to come to a stop just before hitting the object. Assuming standard perception/reaction time, determine the grade of the road.A driver is traveling at 80 kph on a wet road. An object is spotted on the road 125 m ahead and the driver is able to come to a stop just before hitting the object. Assuming standard perception/reaction time, determine the grade of the road.A driver travelling at 50 mph sees a wall at a certain distance ahead. The driver applies the brakes immediately (perception time is 2.5 seconds) and begins slowing the vehicle at 6 m/sec^2. If the distance from the stopping point to the wall is 12 m, how far was the car from the wall upon perception?
