Question 45

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 (4i−3j) m(4\mathbf{i} - 3\mathbf{j}) \text{ m}(4i−3j) m. At time t=3t = 3t=3, P P\,P is at the point B B\,B with position vector (−5i+9j) m(-5\mathbf{i} + 9\mathbf{j}) \text{ m}(−5i+9j) m.
