![### 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.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fbc027c4e-bdfa-4993-8e85-e5bb19c4afed%2F12f89388-202f-4f89-92cd-f7f11de3a8a4%2F2jlancb_processed.jpeg&w=3840&q=75)
