Answer

B. \(43,200 \mathrm{~J}\)

Explain

1. The kinetic energy (KE) of an object is given by the formula \(KE = \frac{1}{2} m v^2\), where \(m\) is the mass of the object and \(v\) is its velocity.2. Plugging in the given values, \(m = 600\) kg and \(v = 12\) 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 \(KE = \frac{1}{2} \times 600 \times 144\)4. \(KE = 300 \times 144\)5. \(KE = 43,200\) J.
