An object moving along horizontal x -direction with kinetic energy 10 J is displaced through x=(3 i ) m by the force F =(-2 i +3 j ) N. The kinetic…
An object moving along horizontal $\displaystyle x$-direction with kinetic energy $\displaystyle 10$ J is displaced through $\displaystyle x=(3 \hat{i}) \mathrm{m}$ by the force $\displaystyle \vec{F}=(-2 \hat{i}+3 \hat{j}) \mathrm{N}$. The kinetic energy of the object at the end of the displacement $\displaystyle x$ is
Official answer
(3)
$\displaystyle 4$ J
