A vehicle is travelling at a speed of 120km/hrs on a roadway segment with 2% upgrade. After the driver started to brake, it took 180meters to come to a full stop. What is the coefficient of friction on this surface? In the previous example, if the coefficient of friction on this surface is 0.3 and the maximum braking distance is 150m, what should be the speed limit?
