    Curvillinear Motion 2

    Ok, this one has got me stumped. I have no idea what to do really.

    Given y^2=7x^3+7x
    where x and y are in meters and y is positive,
    what is the normal component of the acceleration when
    x=3m, x=6m/s, x=4m/s^2

    I found when x = 3, y = 14.491 which i can find the magnitude and angle to plot on the x-axis. And i know i need velocity to define n-t direction, but thats all I got. I guess im confused from how its set out.
    How do i approach this question?

    You need to find an expression for \dot{y}(t), so that you can compute the expressions in the other thread on which you commented. How can you do that, do you think?
