Understanding Momentum

Momentum is a measure of an object's mass in motion. It's calculated using the following formula:

* Momentum (p) = mass (m) * velocity (v)

Calculations

1. Spaceship 1:

* Mass (m1) = 200 kg

* Velocity (v1) = 0 m/s

* Momentum (p1) = m1 * v1 = 200 kg * 0 m/s = 0 kg*m/s

2. Spaceship 2:

* Mass (m2) = 200 kg

* Velocity (v2) = 10 m/s

* Momentum (p2) = m2 * v2 = 200 kg * 10 m/s = 2000 kg*m/s

3. Combined Momentum:

* Total Momentum (p) = p1 + p2 = 0 kg*m/s + 2000 kg*m/s = 2000 kg*m/s

Answer:

The magnitude of the combined momentum of the two spaceships is 2000 kg*m/s.
