Question 42

A particle P P\,P moves with constant acceleration (2i−3j)(2\mathbf{i} - 3\mathbf{j})(2i−3j) ms−2^{-2}−2. At time t=0t = 0t=0, P P\,P has speed u u\,u ms−1^{-1}−1. At time t=2t = 2t=2, P P\,P has velocity (13i+3j)(13\mathbf{i} + 3\mathbf{j})(13i+3j) ms−1^{-1}−1.

Find the value of uuu.
