. A driver traveling at 60 mph rounds a curve on a level grade to see atruck overturned across a roadway at a distance of 400 ft. Is the vehicle able to avoid hittingthe truck? If not, how fast is the vehicle traveling when it strikes the truck? Assume typicalreaction time and rate of deceleration. (Be sure to consider if you should apply stopping sightdistance or decision sight distance.)

Step 1:The initial speed of the truck vi=60mph=360060×5280ft/s=88ft/sdistance of the truck…

What distance will a vehicle travel before coming to a complete stop from a speed of 70 mph, (a) When the vehicle is traveling on a level roadway with no grade, (b-1) When the vehicle is traveling uphill on a roadway of constant grade = 0.10, (b-2) If the roadway grade is not constant but starts at 0.10 uphill and decreases to 0 at a continuous rate, would the braking distance be equal to, greater than, or less than that in the case of a constant 0.10 uphill grade (briefly explain why) (c) When the vehicle is traveling downhill on a roadway of constant grade = 0.10. Assume a perception-reaction time of 2.5 seconds, and an a/g value equal to 0.35.
