To calculate the momentum of the hockey puck, you can use the formula:
\[ \text{Momentum} (p) = \text{mass} (m) \times \text{velocity} (v) \]
Given:
- Mass (\(m\)) = 0.12 kg
- Velocity (\(v\)) = 30 m/s
Now, substituting the values into the formula:
\[ p = 0.12 , \text{kg} \times 30 , \text{m/s} = 3.6 , \text{kg} \cdot \text{m/s} \]
So, the correct answer is:
3.6 kg*m/s
