3) This is an acceleration of velocity. And also there is displacement because the car is moving, changing its position time to time. So, I'd say all the three.
4) deceleration
5) gravity causes it to accelerate.
and the graphs of next questions are not visible. Can you edit and upload again?

In terms of distance, the average speed for the total x miles you'd travel would be 50 miles per hour. However, if you include the fact that you spent less time traveling 60 miles per hour than 40, the average would be closer to 40 than 60 miles per hour.
