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:

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