The figure shows a block of mass $m=20 \mathrm{~kg}$ attached to a pair of identical linear springs, each having a spring constant $k=1000 \mathrm{~N} / \mathrm{m}$. The block oscillates on a frictionless horizontal surface. Assuming free vibrations, the time taken by the block to complete ten oscillations is_____________seconds. (Rounded off to two decimal places)

Take $\pi=3.14$
