The deceleration(negative acceleration) of an automobile in a full skid on the dr pavement is a little greater than one half "g" or half the acceleration you would experience in free fall. Suppose you are going down the high way and you suddenly decide you need to stop your car. your maximum acceleration is 5.5m/s2 (assumed constant) and you travelling at 26.7m/s.
A. What is the minimum time it will take to stop.?
B. What will your average velocity be while stopping?
C. How much distance will it take you to stop?
