Best Answer

Momentum = (mass) x (velocity), in the same direction as the velocity.

Spaceship-1 . . . Momentum = (300) x (2) = 600 kg-m/sec, in some direction.

Spaceship-2 . . . Momentum = (300) x (1) = 300 kg-m/sec, in the same direction.

Their combined momentum = 900 kg-m/sec, in their common direction

but the answer is 1500 kg-ms

Q: Spaceship 1 and Spaceship 2 have equal masses of 300 kg They collide Spaceship 1's final speed is 2 m s and Spaceship 2's final speed is 1 m s in the same direction What is their combined momentum?

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.

900kg-m/s

Momentum is mass multiplied by velocity. The momentum of the two ships would be 300 x 2 = 600 kgm/s and 300 x 1 = 300 kgm/s. So the combined momentum of the two ships would be 900 kgm/s.

The new speed for the combined masses will be one-half the original velocity of the moving spaceship, since the momentum is applied to a mass twice as large.
