A particle P P\,P moves with a constant velocity of (4i−j)(4\mathbf{i} - \mathbf{j})(4i−j) ms−1^{-1}−1.
Show that the speed of P P\,P is 17 ms−1\sqrt{17}\text{ ms}^{-1}17 ms−1.
Find the direction of motion of PPP, giving your answer as a bearing.
Hence find the distance travelled by P P\,P in 4 seconds.
