![3. Stopping Distance: You are traveling at 70 mph on a slushy road (friction coefficient 0.20) when you hear a train whistle. You then see the warning sign that is placed 1000 feet before the gate-protected railroad grade crossing. You know you must try to stop. How close will you be to the gate when you come to a stop? Your reaction time is 1.5 seconds. [F&W 6.18 1976.43 ft]](http://img.homeworklib.com/questions/3280f360-4725-11eb-9063-5769cfeadd74.png?x-oss-process=image/resize,w_560)

A two lane road crosses an at grade railroad track at 90°. If the design speed of the two lane road is 50 mi/h and the velocity of the train when crossing the highway is 90 mi/h, determine the sight distance leg (in ft) along the railroad tracks to permit a vehicle traveling at the design speed to safely cross the tracks when a train is observed at a...

1. Find the stopping sight distance (in feet) for traveling downhill at a grade of 3% and speed of 60 mph, assuming driver’s perception and reaction time of 2.5 sec and a deceleration rate of 9.3 ft/s2. 2. A temporary diversion has been constructed on a highway of +3% grade due to major repairs that are being undertaken on a bridge. The maximum speed allowed on the diversion is 25 mi/h. Determine the minimum distance from the diversion that a...

3. You are driving on the freeway at 80 mph, trailing the car in front of you by two seconds. Suddenly, the car in front of you - also traveling at 80 mph brakes to stop; its tires are new, with a friction coefficient of 0.8. Your car, on the other hand, has poor tires with a coefficient of 0.5. Due to distracting music and passengers, you do not...

As a city planner, you receive complaints from local residents about the safety of nearby roads and streets. One complaint concerns a stop sign at the corner of Pine Street and 1st Street. Residents complain that the speed limit in the area (55 mph) is too high to allow vehicles to stop in time. Under normal conditions this is not a problem, but when fog rolls in visibility can reduce to only 155 ft.155 ft. Since fog is a common...

3. A car traveling at a constant 39 m/s (-87 mph) passes a police car that is initially traveling at 25 m/s (55 mph). At the instant of the pass, the police car accelerates at a constant rate of 3.3 m/s in pursuit. We wish to find how much time elapses before the officer catches the car. (a) Identify the initial states when the car passes the police. (b) Define the final state or conditions which enable...

3. You are an insurance investigator called to the scene of a car accident. According to witnesses, a blue car (mass ms) was traveling south through an intersection when it was hit by a red car (mass m.) traveling east that ran a stop sign. You observe that the red car came to rest in the intersection. The blue car ended up a distance from the intersection, in a direction measured south of east. Determine the...
