    Derivative of Vectors

    How would you find the derivative of the position function r= (8.80 i - 9.00t^2 j) m to find the velocity vector??

    Hello, c_323_h!

    How would you find the derivative of the position function
    r .= .8.80i - 9.00t²j .to find the velocity vector?
    Um, how about differentiating?

    . . v .= .r' .= .0i - 18tj

    Think of it this way...The unit vectors are constants. If you look at it this way, you are just taking the derivative in the usual fashion.
