A particle P P\,P moves with constant acceleration. 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 5 ms-1. 1 second later P P\,P is moving with velocity (−2i+7j) ms−1(-2\mathbf{i} + 7\mathbf{j}) \text{ ms}^{-1}(−2i+7j) ms−1.
Find the acceleration of PPP.
