Spaceship 1 and spaceship 2 have equal masses of 300kg. they collide. spaceship 1s final speed is 2ms and spaceship 2's final speed is 1ms in the same direction. what is their combined momentum?

To find the combined momentum of the two spaceships after the collision, we can use the formula for momentum, which is mass multiplied by velocity (p = mv). For spaceship 1, the momentum is (300 , \text{kg} \times 2 , \text{m/s} = 600 , \text{kg m/s}), and for spaceship 2, it is (300 , \text{kg} \times 1 , \text{m/s} = 300 , \text{kg m/s}). Adding these together, the combined momentum is (600 , \text{kg m/s} + 300 , \text{kg m/s} = 900 , \text{kg m/s}).
