### Problem 14

**Question: What is the total kinetic energy of an object that is 5 kg and moving 25 m/s due West? (2 pts.)**

**Solution:**

The kinetic energy (KE) of an object is calculated using the formula:
\[ KE = \frac{1}{2} mv^2 \]

Where:
- \( m \) is the mass of the object
- \( v \) is the velocity of the object

Alternatively, the formula can be expressed as:
\[ KE = 0.5 \times m \times v \times v \]

Plug in the given values:
\[ KE = 0.5 \times \_\_\_\_\_ \times \_\_\_\_\_ \]

\( \left( \text{Note: Fill in the box with the appropriate numerical values for mass and velocity.} \right) \)

\[ \_\_\_\_\_ \times \_\_\_\_\_ \times \_\_\_\_\_ \times \_\_\_\_\_ = \_\_\_\_\_ \text{ J} \]

The answer is expressed in Joules (J), the SI unit for energy.
