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

Answer 1

The momentum \( P \) of an object can be calculated using the formula:

\[
P = m \times v
\]

where:
- \( m \) is the mass of the object,
- \( v \) is the velocity of the object.

Given:
- Mass \( m = 0.12 \) kg,
- Velocity \( v = 150 \) m/s.

Now, plugging in the values:

\[
P = 0.12 \, \text{kg} \times 150 \, \text{m/s} = 18 \, \text{kg} \cdot \text{m/s}
\]

So, the correct momentum of the hockey puck is:

\[
P = 18 \, \text{kg} \cdot \text{m/s}
\]

Thus, the correct response is:

**P = 18 kg*m/s**
