A motorist travelling at 100 km/hr on a highway needs to take the next exit, which has a speed limit of 50 km/hr. The section of the roadway before the ramp entry has a downgrade of 3% and coefficient of friction (f) is 0.35. In order to enter the ramp at the maximum allowable speed limit, determine the braking distance (expressed in m) from the exit ramp.
1. A driver is travelling  at 50 mph is 80 m from a wall ahead, if the driver applies the brake immediately at t=2 secs, and begins slowing down at 10m/s^2.a. Find the distance from the stopping point to the wall.b. Determine the braking time or the time during deceleration.c. Determine the average skid resistance, assuming brake efficiency of 70%.   2. A two lane road with design speed of 80 kph has horizontal curve of radius 480 m. Design the rate of superelevation. By how much should the outer edges of the pavement be raised with respect to the center line, if the pavement is rotated with respect to the center line and the width of the pavement at the horizontal curve is 7.5 m?
An automobile’s braking distance from 108 km/h is 75 m on level pavement. Assume the braking force is independent of grade. Determine the automobile’s braking distance from 108 km/h when it is going up a 5° incline.    The automobile’s braking distance from 108 km/h when it is going up a 5° incline is _____m.
