Gross weight of an airplane is $7000 \mathrm{~N}$, wing area is $16 \mathrm{~m}^{2}$, and the maximum lift coefficient is 2.0. Assuming density at the altitude as $1.23 \mathrm{~kg} / \mathrm{m}^{3}$, the stall speed (in $\mathrm{m} / \mathrm{s}$ ) of the aircraft is ________________$\quad$ (accurate to two decimal places).
