(B) The reason it is better to attach one end of the carto a heavy object is because it strengthens the tension in thepuller's pull. Therefore, he can apply LESS force to achieve thesame amount of work. Contrary to that if you just pull itout, it's your weight against the car's weight. There's lesstension in your pull.
