20000kg*m/s south
Explanation: Momentum is defined as the amount of movement, and it can be described by the equaton:
P = m*v
Where P is the momentum, m is the mass of the object and v is the velocity.
You can notice that the velocity is a vector (so it has a direction) and also is the momentum (it also has a direction, the same one as the velocity)
so if we have that the velocity is 20m/s south (v is a vector, so i will use south as the direction of the vector), and the mass is 1000kg, the momentum is:
P = 1000kg*20m/s south = 20000kg*m/s south
