Question 27

A toy boat P P\,P moves across a pond with constant velocity. Initially P P\,P is at the point A A\,A with position vector (−2i+7j) m(-2\mathbf{i} + 7\mathbf{j}) \text{ m}(−2i+7j) m. At time t=2t = 2t=2 seconds, P P\,P is at the point B B\,B with position vector (8i−17j) m(8\mathbf{i} - 17\mathbf{j}) \text{ m}(8i−17j) m.
