A 0.40 kg bird is flying at a constant speed of 8.0 m/s. What is the bird's kinetic energy?

Kinetic energy is the energy due to motion of an object

The kinetic energy of the bird is 12.5 joules

Reason:

The known parameter are;

The mass of the bird, m = 0.50 kg

The speed of the bird, v = 8.0 m/s

Required:

To find the kinetic energy of the bird

Solution:

Therefore;

The kinetic energy of the bird is 12.8 J

The correct answer is 12.8 J.

Step-by-step explanation:

To solve this problem, we must remember how to calculate the kinetic energy of an object.

The kinetic energy is represented by the formula K = 1/2 * m * v^2, where m represents the mass of the object and v represents the speed or velocity of the object.  If we plug in the given values into the formula, we get:

K = 1/2 * m * v^2

K = (1/2) * (0.40) * (8.0)^2

Our first step is to square the velocity.  After doing this step, we get the following:

K = (1/2) * (0.40) * (64)

Finally, we can perform the multiplication, to get:

K = 12.8

The unit for kinetic energy is joules, so the correct answer is 12.8 J.

Hope this helps!

u what ?

step-by-step explanation:

answer: the 4 kilogram bag

step-by-step explanation: this is because if you divide the number of kilograms into the total it will tell you how much each individual kilogram would be worth. 2 kilos is 7 and change 3 would be around 6 ish and the 4 kilo would be 4.6 and change and the 5 kilos would be like 4.88
