An airplane of mass $4000 \mathrm{~kg}$ and wing reference area $25 \mathrm{~m}^{2}$ flying at sea level has a maximum lift coefficient of 1.65. Assume density of air as $1.225 \mathrm{~kg} / \mathrm{m}^{3}$ and acceleration due to gravity as $9.8 \mathrm{~m} / \mathrm{s}^{2}$. Using a factor of safety of 1.25 to account
for additional unsteady lift during a sudden pull-up, the speed at which the airplane reaches a load factor of 3.2 is ___________$\quad \mathrm{m} / \mathrm{s}$ (round off to two decimal places).
