d) Determine the safe stopping sight distance while traveling at speed of 60 kmph. Assuming perception and brake reaction time is 2.5 sec. and coefficient of friction varying from 0.40 at 20 kmph to 0.35 at 100 kmph. Case: 1. level Ground 2. Upward gradient of 3%
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-0.32
