Question

A mouse is running across a room with a speed of 2.2 m/s. The mass of the mouse is 1.4 kg. What is the Kinetic Energy of the mouse?

Answer 1

im not sure

Step-by-step explanation:

Answer 2

3.39 J

Step-by-step explanation:

The kinetic energy of an object can be found by using the formula

`k = (1)/(2) m {v}^(2) \\`

m is the mass

v is the velocity

From the question we have

`k = (1)/(2) * 1.4 * {2.2}^(2) \\ = 0.7 * 4.84 \\ = 3.388 \: \: \: \: \: \: \: \: \:`

We have the final answer as

3.39 J

Hope this helps you
