An airplane is cruising at $50\,m/s$ at standard sea level in straight and level flight. The airplane has a wing area of $15\,m^2$ and a wing span of $10\,m$ , and has the maximum gross weight of $1000\,kg$ . The airfoil of the wing has lift slope of $0.102$ per degree and angle of attack at zero lift of $-2.5^{\circ}$ . Considering, $\tau = 0.1$ , find the angle of attack for the wing. Also, find the induced drag for the airplane, if span efficiency factor is $0.6$ .
