The flight speed of the bird reaches 30 m / s. determine the mass of a bird if the kinetic energy is 1800J?
| July 8, 2021 | education
Initial data: V (speed that the bird reaches during flight) = 30 m / s; Q (kinetic energy of a given bird) = 1800 J.
The mass of a given bird can be expressed from the formula for calculating the kinetic energy: Ek = m * V ^ 2/2, whence m = 2Ek / V ^ 2.
Calculation: m = 2 * 1800/30 ^ 2 = 4 kg.
Answer: The mass of a bird is 4 kilograms.
