Paceship 1 and spaceship 2 have equal masses of 300 kg. spaceship 1 has a speed of 0 m/s, and spaceship 2 has a speed of 4 m/s. what is the magnitude of their combined momentum?

Momentum is the product of an object's mass and its speed. Spaceship #1 is completely out of the running ... if it has no speed, then it has no momentum. Spaceship 2's momentum is (300 kg) x (4 m/s) = 1,200 kg-m/s, and that's the total momentum for both of them.

Now I have to ask you: How in the world do you measure their speed ?

Or maybe I should ask: How OUT OF the world do you measure their speed ?

science is a systematic and logical approach to discovering how things in the universe work. true to this definition, science aims for measurable results through testing and analysis. science is based on fact, not opinion or preferences. the process of science is designed to challenge ideas through research.
