Answer

2025 \, \text{J} Explanation 1. Identify the variables Mass m = 4.5 \, \text{kg}, velocity v = 30 \, \text{m/s}. 2. Apply the kinetic energy formula Use **E_{K}=\frac {1}{2}mv^{2}** to calculate kinetic energy. 3. Calculate the kinetic energy E_{K} = \frac{1}{2} \times 4.5 \, \text{kg} \times (30 \, \text{m/s})^2 = 2025 \, \text{J}.
