A particle P P\,P has acceleration [(5t2−10)i+(4t2+6t)j] ms−2[(5t^2 - 10)\mathbf{i} + (4t^2 + 6t)\mathbf{j}] \text{ ms}^{-2}[(5t2−10)i+(4t2+6t)j] ms−2 where t t\,t is the time in seconds. When t=3t = 3t=3 the velocity of the particle is (22i+70j) ms−1(22\mathbf{i} + 70\mathbf{j}) \text{ ms}^{-1}(22i+70j) ms−1
Find an expression for the velocity of P P\,P in terms of ttt
Initially the particle is at the point with position vector (6i−8j)(6\mathbf{i} - 8\mathbf{j})(6i−8j). Find an expression for the displacement of P P\,P in terms of ttt
