28.5 kg*m/s
28.5 kg*m/s

17.5 kg*m/s
17.5 kg*m/s

9 kg*m/s

Answer 1

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**.
