A person walking along a straight line moves such that her velocity as a function of time can be represented by the graph above. At what time does the person have the same position as she had at time t = 0?

• At t = 5 s

• During the interval 5 s < t < 8 s

• At t = 8 s

• During the interval t > 8 s

What is happening at D?

• Stationary
• Accelerating
• Fast steady speed; moving away from the starting position
• Slower steady speed; moving away from the starting position
