Answer 1

To calculate the momentum (P) of the hockey puck, we use the formula:

\[
P = m \times v
\]

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

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

Now we can substitute the values into the formula:

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

Calculating this gives:

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

So, the momentum of the hockey puck is:

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

The correct response is:

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