Two people who weigh the same climb a flight of stairs. The first person climbs the stairs in 30 s, while the second person climbs them in 40s. Which person does more work? Which uses more power?

    Both do the same amount of work. Power is work/unit of time; therefore, the person who climbs faster exerts more power. Check my thinking.
