    The height in meters of a ball dropped from the top of CN tower is given by h(t)= -4.9t^2+450
    find the average velocity for the first two seconds?

    h(0)=-4.9(0)^2+450
    h(0)=450
    h(2)= 430.4
    AROC= 430.4-450/2-0
    AROC= -9.8m/s
    By definition, the answer is given by \frac{h(2) - h(0)}{2 - 0} so assuming that your arithmetic is correct your answer will also be correct.
