    1. The problem statement, all variables and given/known data

    A particle moves along the x axis with velocity vx = (9.7 m/s2)t - 6.0 m/s.
    (b) Sketch vx versus t over the interval 0 < t < 10 s. (Do this on paper. Your instructor may ask you to turn in this work.)

    (c) How do the instantaneous accelerations at the middle of each of the two time intervals specified in Part (a) compare to the average accelerations found in Part (a)?
    3(No Response)
    (a) Find the average acceleration for two different one-second intervals, one beginning at t = 3.0 s and the other beginning at t = 4.0 s.
    aavg, 3.0 to 4.0 s and aavg, 4.0 to 5.0 s

    2. Relevant equations

    AT^2-Bt+c

    3. The attempt at a solution

    238.8 m/s^2

    129.1 m/s^2

    Did you sketch the graph as required? Care to post it. This is a very important step and should not be skipped.
