# Calculate Kinetic Energy of a Bird

## Question:

What is the kinetic energy of a 0.10-kilogram bird flying at a constant speed of 8.0 m/s?

## Answer:

The kinetic energy of a 0.10-kilogram bird flying at a constant speed of 8.0 m/s is 3.2 joules.

## Explanation:

**Kinetic Energy Formula:** The kinetic energy (KE) of a moving object is calculated using the formula KE = 1/2mv^2, where m is the mass of the object and v is its velocity squared.

In this case, we have a bird with a mass of 0.10 kilograms and a constant speed of 8.0 meters per second. To find the kinetic energy, we substitute the values into the formula:

KE = 1/2 x mass x velocity^2

KE = 1/2 x 0.10 kg x (8.0 m/s)^2

KE = 1/2 x 0.10 x 64

KE = 1/2 x 6.4

KE = 3.2 joules

Therefore, the bird's kinetic energy is 3.2 joules, which is the amount of energy it possesses due to its motion at a constant speed of 8.0 m/s.
