imagine a squirrel has a mass of 10 kg and is running at a speed of 3m/s. What is the squirrel's kinetic energy in joules?

Answer 1

The kinetic energy (KE) of an object can be calculated using the formula:

\[ KE = \frac{1}{2}mv^2 \]

where:

• \(m\) is the mass of the object (in kilograms),
• \(v\) is the speed of the object (in meters per second).

For the squirrel with a mass of 10 kg running at a speed of 3 m/s:

\[ KE = \frac{1}{2} \times 10 , \text{kg} \times (3 , \text{m/s})^2 \]

Calculating further:

\[ KE = \frac{1}{2} \times 10 \times 9 \] \[ KE = 5 \times 9 \] \[ KE = 45 , \text{joules} \]

So, the squirrel's kinetic energy is 45 joules.
