To calculate the momentum of the dog, we can use the formula for momentum \( p \):
\[ p = m \cdot v \]
where \( m \) is the mass (in kg) and \( v \) is the velocity (in m/s).
Given:
- \( m = 18 , \text{kg} \)
- \( v = 0.63 , \text{m/s} \)
Calculating the momentum:
\[ p = 18 , \text{kg} \times 0.63 , \text{m/s} = 11.34 , \text{kg} \cdot \text{m/s} \]
Thus, the correct response is:
11.34 kg*m/s
