Charlie is playing with his daughter Torrey in the snow. She sits on a sled and asks him to slide her across a flat, horizontal field. Charlie has a choice of pushing her from behind by applying a force downward on her shoulders at 30° below the horizontal (figure (a)) or attaching a rope to the front of the sled and pulling with a force at 30° above the horizontal (figure (b)). Which would be easier for him?
