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

To find the momentum of the hockey puck, we use the formula for momentum:
\[ P = m \cdot v \]
where:
- \( P \) is the momentum,
- \( m \) is the mass of the puck (0.12 kg),
- \( v \) is the velocity of the puck (150 m/s).
Now, substituting the values:
\[ P = 0.12 \, \text{kg} \times 150 \, \text{m/s} = 18 \, \text{kg} \cdot \text{m/s} \]
Thus, the momentum of the hockey puck is:
\[ P = 18 \, \text{kg} \cdot \text{m/s} \]
Therefore, the correct response is:
**P=18 kg*m/s**
\[ P = m \cdot v \]
where:
- \( P \) is the momentum,
- \( m \) is the mass of the puck (0.12 kg),
- \( v \) is the velocity of the puck (150 m/s).
Now, substituting the values:
\[ P = 0.12 \, \text{kg} \times 150 \, \text{m/s} = 18 \, \text{kg} \cdot \text{m/s} \]
Thus, the momentum of the hockey puck is:
\[ P = 18 \, \text{kg} \cdot \text{m/s} \]
Therefore, the correct response is:
**P=18 kg*m/s**
