A particle P P\,P moves with constant acceleration of i−j\mathbf{i} - \mathbf{j}i−j ms−2^{-2}−2. At time t=0t = 0t=0, the particle is at the origin, OOO, and moving with a velocity of i−2j\mathbf{i} - 2\mathbf{j}i−2j 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 4i−6j4\mathbf{i} - 6\mathbf{j}4i−6j m
