# Max Charge Kinetic Energy

There is a massive charged particle $$(m = \SI{4}{\kg}, q = \SI{2}{\coulomb})$$ at rest at the origin $$(x = \SI{0}{\m})$$ at time $$t = 0$$. The particle is influenced by an electric field oriented purely in the $$x$$ direction. Its value is given by:

$E_x = 3e^{-t} \hspace{0.2cm} \frac{\text{V}}{\text{m}}$

As time tends toward infinity, the particle's kinetic energy converges upon what limiting value (in Joules, to 1 decimal place)?

Note: All physical quantities are in standard SI units.
