Final answer:
To calculate the momentum of the hockey puck, first convert its velocity from 150 mph to meters per second, which is approximately 67.06 m/s. Then, using the mass of the puck (0.12 kg), we find the momentum to be 8.0472 kg*m/s.
Step-by-step explanation:
The momentum of an object is given by the product of its mass and its velocity. To find the momentum p of the hockey puck, we use the formula p = m * v, where m is the mass and v is the velocity. However, we need to convert the velocity from miles per hour (mph) to meters per second (m/s) since standard SI units are used in physics.
First, we convert 150 mph to m/s: 150 mph ≈ 67.06 m/s. Now we can calculate the momentum. Given the mass m of the hockey puck is 0.12 kg, and the converted velocity v is 67.06 m/s, the momentum p is:
p = m * v
p = 0.12 kg * 67.06 m/s
p = 8.0472 kg*m/s
Therefore, the momentum of the hockey puck is 8.0472 kg*m/s.
