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 P=18 kg*m/s P = 18 kg * m / s P=8*10−4 kg*m/s P = 8 * 10 - 4 kg * m / s P=18 N P = 18 N M=18 kg*m/s

The momentum \( P \) of an object can be calculated using the formula:
\[
P = m \cdot v
\]
where:
- \( m \) is the mass of the object,
- \( v \) is the velocity of the object.
For the hockey puck:
- Mass \( m = 0.12 \, \text{kg} \)
- Velocity \( v = 150 \, \text{m/s} \)
Now, substituting the values into the formula:
\[
P = 0.12 \, \text{kg} \cdot 150 \, \text{m/s} = 18 \, \text{kg} \cdot \text{m/s}
\]
So, the momentum of the hockey puck is
\[
P = 18 \, \text{kg} \cdot \text{m/s}
\]
The correct response is \( P = 18 \, \text{kg} \cdot \text{m/s} \).
\[
P = m \cdot v
\]
where:
- \( m \) is the mass of the object,
- \( v \) is the velocity of the object.
For the hockey puck:
- Mass \( m = 0.12 \, \text{kg} \)
- Velocity \( v = 150 \, \text{m/s} \)
Now, substituting the values into the formula:
\[
P = 0.12 \, \text{kg} \cdot 150 \, \text{m/s} = 18 \, \text{kg} \cdot \text{m/s}
\]
So, the momentum of the hockey puck is
\[
P = 18 \, \text{kg} \cdot \text{m/s}
\]
The correct response is \( P = 18 \, \text{kg} \cdot \text{m/s} \).
