1.1. Higher Tier Only

At a paintballing party, a group of children fire paint balls at each other using paintball guns.

The paintball guns have a mass of 0.5 kg each.

Each paintball inside the gun has a mass of 2.5 g.

Explain the momentum of the paintball before the gun is fired.

Use the information above to support your answer.

1.2. Higher Tier Only

The gun fires the paintball forwards at a velocity of 70 m / s.

The paintball has a mass of 2.5 g

Calculate the momentum of the paintball just after the gun is fired.

1.3. Higher Tier Only

Compare the total momentum of the gun and paintball before and after the gun is fired, assuming no other forces were acting on the objects.

Use information from (a) and (b) above in your answer.
