The braking distance of a car from 90 km/h is 40 m assuming the pavement is level. (a) if the pavement is with 5° inclination, what will be the braking distance (in meter) of the car going up from 90km/h? (b) and if the car is going down at 6% inclination, what is its braking distance (in meter) from 90km/h? Note: Assume the breaking force is not dependent of the grade.
