In an oscillating spring$-$mass system with frequency $f,$ the stiffness $(k)$ of the spring is doubled.

The new frequency $f_{\text{n}\text{e}\text{w}}$ is what value in terms of $f_{\text{o}\text{l}\text{d}}?$

Round your answer to two decimal places for entry into Canvas. Enter just the numbers, not placeholders. Example: for $4\mathrm{.}337$k$,$ enter $4\mathrm{.}34.$
