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**
\[
p = m \cdot v
\]
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**
