Answer: graph 6

Explanation:

The car is at first moving at a constant speed and there is no acceleration.

After seeing a patrol car it starts slowing down i.e. decelerating for a short while the car moves at a lower constant speed. At timet2 the car then accelerates to the original constant speed at which it remains.
