A particle P P\,P moves with constant acceleration of i−2j\mathbf{i} - 2\mathbf{j}i−2j ms−2^{-2}−2. At time t=0t = 0t=0, the particle is at the origin, OOO, and moving with a velocity of 2i+j2\mathbf{i} + \mathbf{j}2i+j ms−1^{-1}−1
Find the speed of P P\,P at time t=2t = 2t=2 seconds
Show that the position vector of P P\,P at time t=2t = 2t=2 seconds is 6i−2j6\mathbf{i} - 2\mathbf{j}6i−2j m
