    Calculate the velocity and acceleration of the Medowie Yowie

    Calculate the velocity andacceleration of the Medowie Yowiewhen its position at time t is given by:

    Firstly Medowie is a country town in Australia the lecturer put in on this problem near the university,

    Secondly this has me stumped.

    $g(t)=e^{-t^2/3}$

    $g'(t)=-\dfrac{2t}{3}e^{-t^2/3}$

    chain rule ...

    $\dfrac{d}{dt} e^u = e^u \cdot \dfrac{du}{dt}$, where $u = -\dfrac{t^2}{3}$
