Homework Help: Kinematics position function question

    < Mentor Note -- thread moved to HH from the technical physics forums, so no HH Template is shown >

    I'm studying for AP test. This is not a hw question. Does anyone know how to do number 2? I don't even know where to start. I tried factoring out t and using quadratic formula, but I kept getting imaginary roots and t can't equal zero.

    X = (t^3 - 3t^2 + 6t)m

    where m is meters and t is seconds.
    What is the position of the particle when it is at its minimum speed (after t = 0)

    thanks in advance for anyone that answers.
