Final answer:
The kinetic energy of a 0.10-kilogram bird flying at a constant speed of 8.0 m/s is calculated using the formula KE = \( \frac{1}{2}mv^2 \), resulting in a kinetic energy of 3.2 joules.
Step-by-step explanation:
The kinetic energy (KE) of a moving object depends on both its mass and the square of its velocity, according to the formula KE = \( \frac{1}{2}mv^2 \). In this case, we need to calculate the kinetic energy of a bird with a mass of 0.10 kilograms flying at a constant speed of 8.0 meters per second.
Using the formula:
KE = \( \frac{1}{2} \times 0.10 \text{ kg} \times (8.0 \text{ m/s})^2 \)
KE = \( \frac{1}{2} \times 0.10 \times 64 \)
KE = \( \frac{1}{2} \times 6.4 \)
KE = 3.2 joules
Therefore, the bird's kinetic energy is 3.2 joules.
