You are playing with your daughter in the snow. She sits on a sled and asks you to slide her across a flat, horizontal field. You have a choice of (a). Pushing her from behind by applying a force downward on her shoulders at 30° below the horizontal. (b). Attaching a rope to the front of the sled and pulling with a force at 30° above the horizontal. Which would be easier for you and why?
