    Question a derivative proble,

    Hi!everyone:
    This is first time I make a post here. Please help!
    Here is the question:

    A car accelerates from rest to a maximum velocity at t=45 secs and then decelerates to a stop in t=120 secs. Distance traveled in meters is given by
    s(t)=3t^2-(1/60)t^3, finds'(t) and s''(t)

    your question gives a lot of unnecessary information. to find s'(t) and s''(t), you don't need to know the first sentence.

    anyway, we are simply using the power rule here.

    \frac d{dt}t^n = nt^{n - 1}

    if there is a constant in front, don't worry about it, just take the derivative of the variable part of the function and multiply by the constant when done
