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.

The momentum of an object is given by the formula: momentum = mass x velocity. Therefore, the combined momentum of Spaceship 1 and Spaceship 2 after the collision would be the sum of their individual momentums. Since they have equal masses and are moving in the same direction, you can simply add their individual momentums to get the combined momentum.
Their speed after the collision will be 0 m/s since Spaceship 1 was stationary and Spaceship 2 had no stated speed. The total momentum before the collision is zero, so the total momentum after the collision will also be zero if they stick together.
Multiply mass x velocity for each spaceship. Add the results.
