Two automobiles A and B are approaching each other in adjacent highway lanes. At t=0, A and B are 1km apart, their speeds are 108km/h and 63km/h and they are at the points P and Q respectively. Knowing that A passes point Q 40s after B was there and B passes P 42s after A was there, determine the uniform acceleration of A and B, when the vehicles pass each other and the speed of B at that time.
3. What should be the maximum speed (mph) of a car traveling on a leveled (zero grade) road surface if the available stopping sight distance is 400 ft? Assume 1.5 s of reaction time and braking friction coefficient of 0.35.
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.
Car A experienced engine failure the moment it enters a 2-km highway that has a constant grade of 4 deg throughout its span (4 deg. inclination). Point C is the location where car A experienced failure.

What is the safe maximum speed without tipping or skidding for a 13,200 N automobile running around a flat curve of 80 m radius? Its center of gravity is 0.60 m above the road surface and the wheel tread is 1.5 m, and f = 0.50.
A car is traveling at 76 mi/hr down a 3% grade on poor, wet pavement. The car's braking efficiency is 90%. The brakes were applied 320 ft before impacting an object. The car had an antilock braking system, but the system failed 200ft after the brakes had been applied (wheels locked). What speed was the car traveling at just before it impacted the object? (Assume theoretical stopping distance, ignore air resistance, and let Frl=0.015)
The figure shows two possible paths for negotiating an unbanked turn on a horizontal portion of a race course. Path A-A follows the centerline of the road and has a radius of curvature ρA = 84 m, while path B-B uses the width of the road to good advantage in increasing the radius of curvature to ρB = 212 m. If the drivers limit their speeds in their curves so that the lateral acceleration does not exceed 0.90g, determine the maximum speed for each path.
The car is traveling at a constant speed through a dip in the road. The radius of curvature of the road at point A, the bottom of the dip is 396m. What speed of the car (kph) would result in an acceleration of magnitude 0.2g when the car is at A?
A truck travels along a straight, level road at the speed of 76ft/sec. when the driver is forced to apply the breaks to avoid an accident. If the truck undergoes a constant deceleration of 6ft/sec2, how far does the truck travel before coming to a complete stop?

A car starts from rest at point A and accelerates at 0.75m/s^2 until it reaches a speed of 9m/s. It then proceeds at 9m/s until the brakes are applied. It comes to rest at point B, 27m beyond the point where the brakes are applied. Knowing that the distance between points A and B is 180m, determine the time required for the car to travel from point A to point B
