To calculate the momentum \( p \) of the bowling ball, we can use the formula:
\[
p = mv
\]
where:
- \( m \) is the mass of the bowling ball (8 kg),
- \( v \) is the velocity (9 m/s).
Now, substituting the values:
\[
p = 8 \, \text{kg} \times 9 \, \text{m/s} = 72 \, \text{kg m/s}
\]
Therefore, the momentum of the bowling ball is:
**C. 72 kg m/s**.
\[
p = mv
\]
where:
- \( m \) is the mass of the bowling ball (8 kg),
- \( v \) is the velocity (9 m/s).
Now, substituting the values:
\[
p = 8 \, \text{kg} \times 9 \, \text{m/s} = 72 \, \text{kg m/s}
\]
Therefore, the momentum of the bowling ball is:
**C. 72 kg m/s**.
