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