A dissimulation of birds flying in the sky is going in the same direction with the same speed. Their path covered in 5 seconds is represented on the coordinate scale as $\langle 2,3 \rangle$ with some scale. However, a hawk crosses their path by going just perpendicular to them at the same speed. What vector would represent the path of the hawk in 5 seconds?
