descending a 10% grade at a speed of 75 mi/h, David notices a large object in the roadway ahead of Q3. him. Without thinking about any alternatives, David stabs his brakes and begins to slow down with deceleration of 12 ft/s2. Calculate the minimum distance at which George must have seen the object in order to avoid crashing with it. You can assume that the roadway surface is concrete and that the surface is wet. You can also assume that David has a brake reaction time of 1.1 seconds because he is always alert on this stretch of the road

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.
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)
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.
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.
a truck was travelling uphill at 50kph. the brakes are suddenly applied and the truck stopped in a distance of 16.1m. if the coefficient of friction between the tires and the road surface is 0.4, what is the grade of the road?
An auto, equipped with only front wheel brakes, has a wheelbase of 120 in. with its c.g. located 60 in. ahead of the rear wheels and 36 in. above the pavement. If f = 0.80 at the tires, compute the minimum distance in which the auto can be brought to rest from a speed of 60 mph if the driver’s reaction time before applying the brakes is 3/4 sec.
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. When car A is towed by the truck it gains an acceleration of 3 m/s^2, at the same instance, car B is passing the same highway with a constant velocity of 40 km/hr and is 100m away from point C (measured along the pavement). 1. At what time will car A overtake car B? answer in unit of seconds. 2. How far from point C (along the pavement) will the two cars meet? answer in unit of meters 3. What is the velocity of car A at the instance it overtakes car B? answer in unit of km/hr
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?
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. When car A is towed by the truck it gains an acceleration of 3 m/s^2, at the same instance, car B is passing the same highway with a constant velocity of 40 km/hr and is 100m away from point C (measured along the pavement). 4. Car A will eventually overtake car B. How much time (from the moment the two cars met) will elapse when car A be 50 m away (measured along the pavement) from car B? 5. Car A will eventually overtake car B. At an instance where car A is 50m ahead of car B (measured along the pavement), what is the velocity of car A? answer in km/hr. 6. Car A will eventually overtake car B. At an instance where car A is 50m ahead of car B (measured along the pavement), how far is car B from point C? answer in unit of meters
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.
While traveling at a constant speed a driver saw a road block 112 m away. He applied the brakes and the car decelerated uniformly at 6.4 m/s2. It stopped 5 m from the block. The driver’s PRT is 2.2 seconds. Sketch and calculate the initial constant speed of the vehicle in kph if;a. The roadway is levelb. The roadway grade is +10%c. The roadway grade is -10%
A driver is traveling at 52 mi/h on a wet road. an object is spotted on the road 415 ft ahead and the driver is able to come to a stop just before hitting the object. assuming standard perception/ reaction time and practical stopping distance, determine the grade of the road.
