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

thanks. so all you do is find the derivative of the x and y component? easy enough.
