Question 131 of 183

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 $x=8 \mathrm{~m} ?$
