The position of as a function of time is given by:

\(\vec{r_A} =\) (\(+\)\(t-\)\(t^2)\hat{\imath} + (\)\(+\)\(t-\)\(t^2)\hat{\jmath}\)

’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.

Part 1#

What is the distance between and when \(t\) = ?
