5. The more constant and smooth line is the velocity because the velocity rises quickly and then decelerates very quickly but at a more constant rate compared to the position of the car. 6. The net force on the car is greatest when the car is decelerating when hitting the object because it decelerates rapidly in a short period of time with a lot of high forces acting on it. 7. You can get acceleration if you take time and compare the velocity increase on the graph and then you have the acceleration. 8. The slope of the X axis is about 0 because it is fairly level and this relates to the velocity because it is slowing down. 9. The mistake is that the velocity never goes down to zero meaning that it always kept going very fast even when stooped in the crash
