The momentum \( p \) of an object is calculated using the formula:
\[ p = m \times v \]
where \( m \) is the mass of the object and \( v \) is its velocity.
For the dog:
- Mass \( m = 18 \) kg
- Velocity \( v = 0.5 \) m/s
Now we can calculate the momentum:
\[ p = 18 , \text{kg} \times 0.5 , \text{m/s} = 9 , \text{kg*m/s} \]
Therefore, the momentum of the dog is 9 kg*m/s.
