A vehicle hit a big tree near the edge of highway pavement. Based on the conditions of damages on the vehicle, the estimated speed when the vehicle hit the tree was 20 mile/hr. The observed skid mark on the pavement was 350 ft. The grade of the highway is 3% downward and F=0.35. What is the initial speed of the vehicle right before the driver pushed the brake ?

part a, assuming decelerat on rate is unknown bu the friction factor=0.2. 2. A driver traveling down a 4% grade collides with a roadside object. The roadway has a posted speed limit is 60mph. The driver mentioned he strictly followed the speed limit. The accident investigation team indicates: braking skid marks started 300 ft before the struck object. a. If the friction factor was measured as 0.2, estimate the speed of the vehicle when it struck the object. b. Estimate the minimum required friction factor so the 300 ft skid marks can allow the driver to safely stop before he would strike the object.
A driver traveling down a 4% grade collides with a roadside object in rainy conditions, and is issued a ticket for driving too fast for conditions. The posted speed limit is 65 mi/h. The accident investigation team determined the following: The vehicle was traveling 40 mi/h when it struck the object, braking skid marks started 205 ft before the struck object, the pavement is in good condition, and the braking efficiency of the vehicle was 93%. Using theoretical stopping distance, assuming aerodynamic resistance is negligible, and with the coefficient rolling resistance approximated as 0.015, should the driver appeal the ticket? Why or why not?
On an accident inspection, average skid marks were found to be 65’. The damage inspection hinted at a speed range of 25-35mph at impact. If f=0.7, level roadway, and posted speed was 45mph, what is, in your opinion, the possible cause of the accident?
An accident investigator estimates that a vehicle hit an advertisement column at a speed of 30 mi/h, based on his assessment of damage. Leading up to the accident location, he observes skid marks of 100 ft on the pavement (F = 0.35), 10 ft on the shoulder (F=0.3), and 75 ft on the grass shoulder (F = 0.25); the grades of the pavement, the shoulder and the grass are 2%, 8% and 6% downgrade, respectively. If the post speed of this highway is 60 mi/h, does the initial speed of the driver is one of the accident cause? i need solutions in 10 minutes please
On a single directioned and 5% graded descending highway section, a vehicle is moving with a velocity of 60 km/h. Meanwhile another vehicle moving on the opposite direction is approaching with a velocity of 40 km/h. What is the minimum sight distance to avoid vehicles crashing each other ?Given: Pavement sliding coefficient, f=0,60; detection-reaction time for each driver, tr=1,0 sec.
A car hits a tree at an estimated speed of 32 mph on a 3% downgrade. If skid marks are observed for a distance of 130 feet on a dry pavement (a= 15.5 feet/sec2), followed by 210 feet on a grass-stabilized shoulder (a= 7.6 feet/sec2), estimate the initial speed of the vehicle.
How does the maximum side friction available on a roadway change as vehicle speed increases? O No clear relationship Decreases Increases
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 Pajero intercooler skidded into an intersection of Magsaysay Avenue and Quirino Avenue and stuck a bystander and continued until it hit one of the column support of the skyway. Based on the damage to the front of the car, the police report estimated that the car was doing 8 kph at the moment the impact on the column support. The length of the skidmarks was recorded to be 40m. The road has a downhill grade of -5%. A test car skidded 14m on the same section of the road when the brake is applie from a speed of 40 kph to the halt. Determine the probable speed of the car involved in the accident when the brakes were applied in kph.
Problem 2. A car hits a tree at an estimated speed of 25 mph on a 3 % upgrade. If skid marks of 120 ft are observed on dry pavement (coefficient of braking friction, fb =0.35) followed by 250 ft (fb =0.25) on a grass stabilized shoulder, estimate the initial speed of the vehicle just before the pavement skid began.
A vehicle travelling at 50kph was stopped within 6.50 seconds after application of breaks. Determine the average skid resistance
Given the following data: SSD = 430’ G = +3% Tpr = 2.5 sec Will the speed/velocity be acceptable if the road is generally posted at 30kph? Why or why not?
