Question

section 3
answer
john is moving out of his apartment on a hot, july day to atlanta.
when the moving truck arrives, johns cousin, melanie, is pushing the boxes up the moving ramp provided on the back of the truck.
john starts loading boxes onto the back of the moving truck by picking them straight up and lifting them into the truck.
6 which statement below best describes the trade-off that is happening?
a melanie does more work than john because she moves the boxes a larger distance by using the ramp to move the boxes
b there is no trade-off; both john and melanie have to exert the same force on the boxes since they end up at the same height
c john doesnt have to exert as much force because the distance from the ground directly to the truck is shorter
d melanie can exert less force on the boxes because the distance of the ramp is longer than the distance from the ground directly to the truck

Answer:

D. Melanie can exert less force on the boxes because the distance of the ramp is longer than the distance from the ground directly to the truck.
