Which is the best example of forces acting in the same direction?

Forces act in the same direction when they push or pull an object along the same line and toward the same way. Two football players pushing a tackling sled together can both push it forward, so their forces add. In tug-of-war, the dogs pull in opposite directions, and the other examples do not clearly show two forces working together in the same direction.
