3) Ben and Jerry are movers for Super Duper Moving company. They are arguing about the need for the ramp. Ben says that they do not need the ramp because the height to the truck is the same, so they will do the same amount of work to lift boxes straight up into the truck as to slide them along the ramp into the truck. Jerry says that the ramp will be less work because the angle of the ramp reduces the amount of work needed to get the boxes in the truck. He says he knows this because he is more exhausted lifting boxes without the ramp. Please, use your physics knowledge to settle the debate.
