A car is moving along a straight horizontal road with constant deceleration 0.8 m s−2^{-2}−2.
The car passes the point A A\,A with speed 12 m s−1^{-1}−1 and later passes the point B B\,B with speed 4 m s−1^{-1}−1.
Find the time taken by the car to travel from A A\,A to BBB.
Find the distance ABABAB.
