The kinetic energy (KE) can be calculated using the formula:
\[ KE = \frac{1}{2} m v^2 \]
Where:
- \( m \) is the mass (625 kg)
- \( v \) is the speed (18.3 m/s)
Plugging in the values:
\[ KE = \frac{1}{2} \times 625 , \text{kg} \times (18.3 , \text{m/s})^2 \]
Calculating it step by step:
- Calculate \( (18.3 , \text{m/s})^2 = 334.89 , \text{m}^2/\text{s}^2 \)
- Then, calculate \( \frac{1}{2} \times 625 \times 334.89 = 104,099.0625 , \text{J} \)
Rounding to three significant figures, the kinetic energy is:
104,000 J (joules).
