    The four question that follow belong to the graph being described. The graph has velocit on the y axis in m/s and the x axis is time in seconds. The points given make the grph line. Points (0,20), (2,30), (4,40), (6,40), (8,0), and (10,-30).

    1) What is the velocity of the object at t=2 seconds?

    a) 30m/s
    b) -30m/s
    c) +5m/s
    d) -5m/s
    e) none of above

    2) What is the acceleration of the object at t=2 seconds?

    a) 30m/s
    b) -30m/s
    c) +5m/s
    d) -5m/s
    e) none of above

    3) At what time is the magnitude of the velocity the greatest?

    a) between 0 and 4 seconds
    b) between 4 and 6 seconds
    c) at 6 seconds
    d) between 6 and 8 seconds
    e) between 8 and 10 seconds

    4) At what time is the magnitude of the acceleration the greatest?

    a) between 0 and 4 seconds
    b) between 4 and 6 seconds
    c) at 6 seconds
    d) between 6 and 8 seconds
    e) between 8 and 10 seconds
