The car starts out with a speed of zero and has a constant/uniform acceleration. Which of the following velocity vs. time graph shapes could be for the car? 

• 

• 

• 

• 

The intersection of the two lines on the velocity vs. time graph indicates...

• The time when the car and truck both traveled the same distance

• The time when the car and truck were both going at the same speed

• The time when the car passed the truck

At the point where the car catches up, so that the truck and the car have both traveled the same distance 

• The graphs will cross

• The graphs will have the same area

• The graphs will have the same slope

Which of the images below indicates the correct position of the truck (red) and the car (green) and the correct relative speeds of both vehicles at the time indicated (where the two lines intersect)?
