A particle P P\,P moves in a straight line with constant velocity. Initially P P\,P is at the point A A\,A with position vector (2i−5j) m(2\mathbf{i} - 5\mathbf{j}) \text{ m}(2i−5j) m. At time t=4t = 4t=4 seconds, P P\,P is at the point B B\,B with position vector (−10i+11j) m(-10\mathbf{i} + 11\mathbf{j}) \text{ m}(−10i+11j) m.
