Kinetic Energy of Airplane

The airplane Lockheed Martin C-5M Galaxy with a mass of $380\,\mathrm{t}$ accelerates until it reaches its traveling speed of around $833\,\mathrm{km/h}$. What is the kinetic energy of the airplane during the flight? Solution

The kinetic energy is given as $$E_\mathrm{kin} = \frac{1}{2}\cdot 380,000\,\mathrm{kg} \cdot\left(231.38\,\frac{\mathrm{m}}{\mathrm{s}}\right)^2 = 10.2\,\mathrm{GJ}$$
