To find the required kinetic energy of a given jet plane, we will use the formula: Ek = m * V ^ 2/2.

Values of the variables: m is the mass of the jet aircraft (m = 50 t; in SI m = 50 * 10 ^ 3 kg); V – speed of movement (V = 300 m / s).

Let’s perform the calculation: Ek = m * V ^ 2/2 = 50 * 10 ^ 3 * 300 ^ 2/2 = 2.25 * 10 ^ 9 J = 2.25 GJ.

Answer: The kinetic energy of a given jet is 2.25 GJ.
