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 15 ms-1. 6 seconds later P P\,P is moving with velocity (−12i+6j) ms−1(-12\mathbf{i} + 6\mathbf{j}) \text{ ms}^{-1}(−12i+6j) ms−1.
Find the acceleration of PPP.
