    Answer:A particle has zero velocity initially (i. e., at time

    t=0

    t=0

    ) and its acceleration at

    t

    t

    seconds is

    a (t) = 72t-4

    t

    3

    a (t) = 72t-4t3

    meters-per-second per second. During the time interval

    [5,8]

    [5,8]

    seconds find the average acceleration and the average speed of the particle. I got the average acceleration by taking the integral and then plugging that into

    f (8) - f (5) / 8-5

    f (8) - f (5) / 8-5

    but I have tried working through the average speed and I can't find the answer for that one.
