The total weight is 50 tons, compared to the pilot’s jet speed of 300 m / s. The airplane’s kinetic energy is what?
| May 3, 2021 | education
To find out the kinetic energy of the specified jet, consider the formula: Ek = 0.5 * mрс * V ^ 2, where mрс is the total mass of the specified jet aircraft (mрс = 50 t, in the SI system mрс = 5 * 10 ^ 4 kg); V – flight speed (V = 300 m / s).
Let’s perform the calculation: Ek = 0.5 * mrs * V ^ 2 = 0.5 * 5 * 10 ^ 4 * 3002 = 2.25 * 10 ^ 9 J.
Answer: The required kinetic energy of the said jet should be 2.25 GJ.
