Which is the best example of force acting in the same direction

B. Two football players pushing a tackling sled.

Explanation: Because it asks what is the best example of forces acting in the SAME direction, it will be two football players pushing a tackling sled. This means, since the two football players are both pushing the sled, they will also be pushing it at the same time in the same direction.

Hope this helped. :)

think about the oscillation of the toy shown in the video. when the toy is at the highest point of its motion, its velocity is zero and its acceleration is negative.
