Understanding Momentum

Momentum (p) is a measure of an object's mass in motion. It's calculated by the following formula:

* p = mv

Where:

* p = momentum (measured in kg*m/s)

* m = mass (measured in kg)

* v = velocity (measured in m/s)

Calculation

1. Identify the given values:

* Mass (m) = 920 kg

* Velocity (v) = 25 m/s

2. Plug the values into the momentum formula:

* p = (920 kg) * (25 m/s)

3. Calculate the momentum:

* p = 23,000 kg*m/s

Answer: The momentum of the 920-kg car moving at 25 m/s is 23,000 kg*m/s.
