Question

Two girls each carry a box up to the fourth floor of a building. The total mass of each girl and the box she is carrying is the same. Rachel makes the trip in 35 seconds while Madison takes 50 seconds.

Which of the following statements best describes this task?

a. Rachel has greater power output than Madison.
b. Madison has a greater power output than Rachel.
c. Madison does more total work than Rachel.
d. Rachel does more total work than Madison.

Answer 1

I would say option A. because, considering that Rachel does the work faster than Madison, she has more power being exerted, or output.

Answer 2

The total work is the same for both girls. The one with the shorter time is higher power output.
