The driver of an automobile, which travels with a velocity of
110 km/h on an a 8% graded
descending section of an asphalt paved straigth highway on a rainy
day, recognizes a
pedestrian crossing the street 100 meters away and applies the
brake.
a) Determine whether the accident occurs or not.
b)If the driver is crashing with the pedestrian, what would be the
maximum velocity to
avoid the accident ?
Given: Pavement sliding friction coefficient, f= 0,30;
detection-response time, tr= 1 sec.
