    The graph on the page is a velocity versus time graph. Time is in seconds. The graph has points at (0,20),(5,40),(10,60),(15,80),(15,60),(15,40),(15,20),(15,0),(15,-20),(15,-40),(20,-40),(25,0),(30,0).

    The questions below go with the graph.

    1) Based on the graph of velocity versus time, what is the acceleration at t=10 seconds?

    4.0 m/s^2
    5.3 m/s^2
    6.0 m/s^2
    60 m/s
    none of above

    2)If the initial position of the object is 50 meters at t=0 seconds, what is the position of the object at 30 seconds?

    450 meters
    500 meters
    1050 meters
    1100 meters
    none of these

    3) What was the average velocity of the object from zero to 30 seconds?
    15 m/s
    16.7 m/s
    35 m/s
    36.7 m/s
    none of these

    4) Select all times when the acceleration is positive.

    From 0 till 15 seconds
    From 15 till 20 seconds
    From 20 till 25 seconds
    From 25 till 30 seconds

    5) At what time is the object the furthest away from its starting point at t=0?

    10 seconds
    15 seconds
    20 seconds
    25 seconds
    30 seconds
