A particle P P\,P of mass 0.4 kg moves under the action of a single constant force F\mathbf{F}F newtons. The acceleration of P P\,P is (6i+8j) m s−2(6\mathbf{i} + 8\mathbf{j}) \text{ m s}^{-2}(6i+8j) m s−2.
Find the angle between the acceleration and i\mathbf{i}i.
Find the magnitude of F\mathbf{F}F.
At time t t\,t seconds the velocity of P P\,P is v m s−1\mathbf{v} \text{ m s}^{-1}v m s−1. Given that when t=0t = 0t=0, v=9i−10j\mathbf{v} = 9\mathbf{i} - 10\mathbf{j}v=9i−10j, find the velocity of P P\,P when t=5t = 5t=5.
