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

P=18 N
P = 18 N

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

Answer 1

The momentum (P) of an object is calculated using 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)

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

Now we can calculate the momentum:

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

So, the correct response for the momentum of the hockey puck is:

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