To determine

(a)

In case of heavy damping $\left(c>c_c\right)$, a body never pass through its position of equilibrium $O$ if it is released with no velocity from an arbitrary position.

To determine

(b)

In case of heavy damping $\left(c>c_c\right)$, a body never pass through its position of equilibrium $O$ if it started from $O$ with an arbitrary initial velocity.
