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

a boy lifting his chest off the ground during a pushup

two football players pushing a tackling sled

a person pulling out a garden hose from its reel

two dogs playing tug-of-war with a rope

B : Took the test that was correct

The correct answer would be option B. The best example of forces acting in the same direction would be the two football players pushing a tackling sled. They apply force to the same direction the sled moves. The first option, would have force that are in opposite directions. The force up from lifting and force down from pushing. The third option as well would have forces that are in opposite direction. There is a force towards the person and away from the person. This is the same situation for the two dogs playing tug-of-war with a rope. They exerted forces towards each other.
