Consider a light, single$-$engine airplane, such as the Piper Super Cub. If the maximum gross weight of the airplane is $6700$ N $,$ the wing

area is $35m^2,$ and the maximum lift coefficient is $2\mathrm{.}1$ with flaps down, calculate the stalling speed at sea level. Assume ${}_{}=1\mathrm{.}225$

$k\frac{g}{m^3}.$

The stalling speed at sea level is

$k\frac{m}{h}.$
