Why does ball 1 have a momentum of 0 kgm/s after the collision?

• Because momentum was destroyed

• Because it stopped moving

What will be the total final momentum of the system?

• Zero. Momentum is conserved so the final total momentum is equal to the initial total momentum

• Greater than zero because they are moving. Momentum was created.
