A $5\mathrm{.}00$ kg block on a flat smooth surface is connected to a light horizontal spring $($k$=300$ N$/$m$).$ The spring is initially at its equilibrium position, and the block is at rest. A student then comes along and pulls the block horizontally and stretches the spring out. When she stretches the spring out by $22\mathrm{.}0$ cm$,$ she holds the block there at rest. How much work $($J$)$ did the spring do on the block? Give answer to two places to the right of the decimal.
