Two cars are traveling on level terrain at 60 mi/h on a road with a coefficient of adhesion of 0.8. The driver of car 1 has a 2.5-s perception/reaction time and the driver of car 2 has a 2.0-s perception/reaction time. Both cars are side by side and the drivers are able to stop their respective cars in the same amount of distance after first seeing a roadway obstacle (perception/reaction plus vehicle stopping distance). If the braking efficiency of car 2 is 0.75, determine the braking efficiency of car 1. (Assume minimum theoretical stopping distance and ignore aerodynamic resistance.)
One of the two motor vehicles is moving up the ramp at 90 km / h on a road with a slope of 3%, the other goes down the ramp at a speed of 20 km / h on the opposite lane.
