A particle P P\,P moves with constant acceleration (−4i−12j) ms−2\displaystyle (-4\mathbf{i} - \frac{1}{2}\mathbf{j}) \text{ ms}^{-2}(−4i−21j) ms−2. At time t=0t = 0t=0, P P\,P is moving in the direction (4i+3j)(4\mathbf{i} + 3\mathbf{j})(4i+3j) with speed 15 ms-1.
Find the velocity of P P\,P 6 seconds later.
