A spring $/$ mass system is shown in four different states.

State A: The spring hangs vertically in equilibrium with no mass at its end.

State B: A $3\mathrm{.}3$ kg mass hangs from the spring in equilibrium, stretching the spring $6\mathrm{.}1$ cm $($b$).$

State C: The mass is pulled down and released from a distance, c$,$ below the equilibrum position of the spring.

State D : The spring is at its equilibrium length and the mass has a speed, v$,$ of $9\mathrm{.}2$m$//$s$.$

How far was the spring stretched below the equilibrium position $($c$)$ in State C before the mass was released?
