A particle which is experiencing a force, given by $\displaystyle \vec{F}=3 \vec{i}-12 \vec{j}$, undergoes a displacement of $\displaystyle \vec{d}=4 \vec{i}$. If the particle had a kinetic energy of $\displaystyle 3$ J at the beginning of the displacement, what is its kinetic energy at the end of the displacement ?
