Answer:

400 kg.m/s

Explanation:

In a closed system, the principle of conservation of momentum applies. It means. the total momentum before collision equals to the total momentum after collision hence since the initial momentum is given as 400 kg.m/s, the final sum will be the same.

Answer:

400 kg•m/s north
