Answer

B.

Explanation

1. The kinetic energy (KE) of an object is given by the formula , where is the mass of the object and is its velocity.2. Plugging in the given values, kg and m/s, we get: \(KE = \frac{1}{2} \times 600 \text{ kg} \times (12 \text{ m/s})^2\)3. Calculating the above expression, we get 4. 5. J.
