Understanding Momentum

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

* p = m * v

* where:

* p = momentum

* m = mass

* v = velocity (speed and direction)

Solving for Speed

1. We know:

* Momentum (p) = 600 kg-m/s

* Mass (m) = 300 kg

2. Rearrange the momentum equation to solve for velocity (speed):

* v = p / m

3. Substitute the values:

* v = 600 kg-m/s / 300 kg

4. Calculate the speed:

* v = 2 m/s

Answer: The speed of Spaceship 1 and 2 is 2 m/s.
