The image was designed as part of a physics course where the idea is to find the net force. Quite obviously, this is 50N. Not as obvious…
Who is the hero?
Hint
What makes a story compelling is when we empathize with the hero and what they want, and feel the fear that they will not get what they want. Therefore, when there are multiple options for the hero, consider who faces the greatest obstacle.
Answer
The hero is the player on the left who kicks with a force of 75N. This is because what makes a story compelling is the extent to which the obstacle seems insurmountable.
However… if you were storytelling for business, it’s possible you might approach this differently. Depending on your objective, you might position the story with the player on the left or the right as the hero.
To be clear, from an entertainment perspective, if the hero is the player on the right, it’s not a compelling story (and thus, not really a story at all). That 50N difference means the player on the right is kicking 67% harder. “Hero easily gets what he wants” isn’t a recipe for box office success.
