A particle P P\,P moves with a constant velocity (2i+2j) ms−1(2\mathbf{i} + 2\mathbf{j}) \text{ ms}^{-1}(2i+2j) ms−1 with respect to a fixed origin OOO. It passes through the point A A\,A whose position vector is (1i+8j) m(1\mathbf{i} + 8\mathbf{j}) \text{ m}(1i+8j) m at t=0t = 0t=0.
Calculate the distance of P P\,P from O O\,O when t=2t = 2t=2.
