A Ford Everest skidded into a intersection of Maharlika Highway and Circumferential Road and struck a bystander and continued until it hit one of the electrical post of the highway. Based on the damage to the front of the Everest, the police report estimated that the car was doing 8 kph at the moment of impact on the electrical post. The length of the skid marks was recorded to be 40 m. The road has down hill grade of 5% A test car skidded 14 m. on the same section of the road when the brake is applied from a speed of 40 kph to the halt. Determine the probable speed of the car involved in the accident when the brakes where applied in kph?

A car running at 80kph saw an oil truck in an accident 250 meters away. At the same time the truck is spilling oil causing a 60% reduction of friction. If initial f=0.30 a) will the car hit the obstruction? b) assuming that the tires would be replaced in such a way that the f=0.70, how much distance will the car have away from the obstruction? c) If the obstruction is 120m away and the oil did not spill, what would have been a safe speed at which the car will not hit the obstruction from 10m away assume f=0.3
A six-lane recreational freeway has the following characteristics:• 12 ft lanes• 6 ft right-side lateral clearance• 2 ramps/mile• 10% trucks (standard mix, which means for freeways is 70% SUTs/30%TTs))• PHF = 0.95• Level terrain• Peak hour demand = 4,000 veh/hBecause the facility services recreational users to a nearby ski area, the peak period occurs on weekends, and lightto moderate snow is the normal weather pattern. If virtually all uses of the facility are unfamiliar with theroadway, what is the expected LOS during the peak period?
An inexperienced driver of an all-wheel drive car applies too much throttle in an attempt to accelerate from rest up the slippery 10 percent incline. The result is a wheel spin on all four tires, each of which have the same gripping ability. Determine the vehicle acceleration for the conditions where the tire on the surface have uk = 0.012.
Aloha! This question I'm stuck on in my class. COuld you help? A driver traveling North on a two-lane two-way highway is performing apassing maneuver (i.e., using the opposing traffic lane) at a speed of v1 = 100 km/h on a sectionof the road with a grade G1 = 4%. Her perception-reaction time is tr1 = 1.0 s and her car canperform the stopping maneuver with a friction coefficient f1 = 0.35 (assuming, for example, worntires). The driver of another car traveling South at a speed v2 = 90 km/h has a perception-reactiontime tr2 = 1.3 s. Since the tires of this vehicle, which is traveling on a grade G2 = -4.0%, are ingood condition, they can develop a coefficient of friction f2 = 0.52. The two vehicles becomevisible to one another at the same time, when they are separated by a distance X = 200 m, measuredfrom front bumper to front bumper (See sketch below). Recall that g = 9.81 m/s2and that 3.6 km/h= 1 m/s.Assuming that the only alternative for the two drivers to avoid a collision is to…
