Momentum = (mass) x (velocity), in the same direction as the velocity.Spaceship-1 . . . Momentum = (300) x (3) = 900 kg-m/sec, in some direction.Spaceship-2 . . . Momentum = (300) x (2) = 600 kg-m/sec, in the same direction.Their combined momentum = 1,500 kg-m/sec, in their common direction.

Momentum = (mass) x (velocity), in the same direction as the velocity.Spaceship-1 . . . Momentum = (200) x (0) = 0 kg-m/sec, in some direction.Spaceship-2 . . . Momentum = (200) x (6) = 1200 kg-m/sec, in the same direction.Their combined momentum = 1200 kg-m/sec, in their common direction.

Momentum = (speed) times (mass).Spaceship-1 has no momentum, since its speed is zero. The combined momentum is just the momentum of Spaceship-2.Momentum of Spaceship-2 = (m V) = 300 x 4 = 1,200 kg-meters

1800 kg-m/sec 600 kg x 3 meters/sec (in the direction spaceship 2 was headed). Since the first spaceship had all the initial momentum, only the velocity of the combined mass will change.

Momentum = mass x speedSince Spaceship-#1 is not moving, it has no momentum. Their combined momentumis that of Spaceship-#2 alone.Momentum = mass x speed = 200 x 10 = 2,000 kilogram-meters per second.

Multiply mass x velocity for each spaceship. Add the results.

600kg-m/s apex miles

The idea is to calculate the momentum for each one, then add the two together. As a reminder, momentum is the product of speed x mass.

2,000 kg-m/s

momentum = mass × velocity Assuming they are separate, the total momentum is 200 kg × 0 m/s + 200 kg × 10 m/s = 2000 kg m/s
