Miko is blowing up balloons for her little sister’s birthday party. One of the balloons slips out of her hand before she ties it off, and it shoots through the air until it is empty. Which statement explains what caused the balloon to accelerate?
The air leaving through the balloon's mouth pushes on the air surrounding the balloon, so the balloon experiences a net force.
