A spring$-$mass setup with force constant k$=0\mathrm{.}500$k$=0\mathrm{.}500[$N$/$m$]$ and mass m$=4\mathrm{.}00$m$=4\mathrm{.}00[$kg$]$ is submerged in water for an experiment. The water dissipated the oscillation of the mass with damping coefficient b$=4\mathrm{.}00$b$=4\mathrm{.}00[$kg$/$s$].$ Which of the following best describes the motion of the mass?

The mass oscillates with constant amplitude.

The mass does not oscillate and returns to equilibrium relatively fast.

The mass does not oscillate and returns to equilibrium relatively slow.

The mass oscillates with decreasing amplitude.
