What is the kinetic energy of a 2 kg bird flying at a speed of 3 m / s?
| September 8, 2021 | education
For a closed system, the kinetic energy of a bird can be calculated using the formula:
Ek = (m * V ^ 2) / 2, where Ek is the kinetic energy of the bird (J), m is the mass of the bird (m = 2 kg), V is the speed of the bird (V = 3 m / s).
Let’s calculate the kinetic energy of the bird:
Ek = (m * V ^ 2) / 2 = (2 * 3 ^ 2) / 2 = 9 J.
Answer: The kinetic energy of the bird is 9 J.
