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)

Question

Responses

P=18 N
P = 18 N

M=18 kg*m/s
M = 18 kg * m / s

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

P=8*10−4 kg*m/s

Answer 1

To calculate the momentum (P) of an object, you can use the formula:

\[ P = m \times v \]

where:

• \( m \) is the mass of the object (in kg),
• \( v \) is the velocity of the object (in m/s).

For the hockey puck:

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

Now, substituting the values into the formula:

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

So the momentum of the hockey puck is \( P = 18 , \text{kg} \cdot \text{m/s} \).

The correct response is:

P = 18 kg*m/s
