a rocket with a mass of 1,000 kilograms is moving at a speed of 20 meters per second. the magnitude of the momentum is

20,000 kg m/s.

Explanation:

Momentum can be calculated with the formula: p=mv, where m is the mass, and v is the velocity.

In this case, we have: p=1000(20), or 20,000 kg m/s.

Let me know if this helps!
