1. pushing a box of math books weighing 600 newtons a distance of 20 meters
2. pulling a television weighing 400 newtons down a hallway of 35 meters
3. pushing a stalled truck weighing 7,500 newtons a distance of 0.4 meters
4. carrying several textbooks weighing 130 newtons, over the course of a semester, for 5,000 meters
