A particle with a mass of 1 kg is having a velocity of 10 m$$s^{-1}$$ in +ve x-direction at t=0 . Forces $$F_{1}$$ and $$F_{2}$$ act on the particle whose magnitude are changing with time according to the variation shown In figure. The magnitude of the velocity of the particle at t=3 s(neglect gravity effect) is found to be n$$\sqrt{5}$$ m$$s^{-1}$$ . Find the value of n .
