Physics - W.E.P. Question with Solution | TestHub

The force $\vec{F}=F\hat{i}$ on a particle of mass $2\mathrm{kg}$, moving along the $x$-axis is given in the figure as a function of its position $x$. The particle is moving with a velocity of $5\mathrm{m}/\mathrm{s}$ along the $x$-axis at $x=0$. What is the kinetic energy of the particle at $x=8\mathrm{m}?$
