Distance Between Two People#
The position of Santiago as a function of time is given by:
\(\vec{r_A} =\) (\(+\)\(t-\)\(t^2)\hat{\imath} + (\)\(+\)\(t-\)\(t^2)\hat{\jmath}\)
Ximena’s position is given by:
\(\vec{r_B} =\) (\(+\)\(t-\)\(t^2)\hat{\imath} + (\)\(+\)\(t+\)\(t^2)\hat{\jmath}\).
The positions \(\vec{r_A}\) and \(\vec{r_B}\) are in meters and \(t\) is in seconds.
