Question
A hockey puck with a mass of 0.12 kg is traveling across the ice at a velocity of 150 m/s downfield. What is the momentum of the hockey puck?(1 point) Responses M=18 kg*m/s M = 18 kg * m / s P=8*10−4 kg*m/s P = 8 * 10 - 4 kg * m / s P=18 kg*m/s P = 18 kg * m / s P=18 N

To find the momentum (P) of an object, we use the formula:
\[ P = m \times v \]
where \( m \) is the mass and \( v \) is the velocity.
For the hockey puck:
- Mass (m) = 0.12 kg
- Velocity (v) = 150 m/s
Now, let's calculate the momentum:
\[ P = 0.12 \, \text{kg} \times 150 \, \text{m/s} \]
\[ P = 18 \, \text{kg} \cdot \text{m/s} \]
So, the correct response is:
**P = 18 kg*m/s**
\[ P = m \times v \]
where \( m \) is the mass and \( v \) is the velocity.
For the hockey puck:
- Mass (m) = 0.12 kg
- Velocity (v) = 150 m/s
Now, let's calculate the momentum:
\[ P = 0.12 \, \text{kg} \times 150 \, \text{m/s} \]
\[ P = 18 \, \text{kg} \cdot \text{m/s} \]
So, the correct response is:
**P = 18 kg*m/s**
