Question

Let’s say a small person with a mass of 50 kg walks up two flights of stairs. A heavy person with a mass of 105 kg walks up the same stairs. Who did more work and why?

Please help me, I'm very confused

Answer 1

Heavier person

Step-by-step explanation:

Work = force × distance. In this case, force = weight and distance = height of the stairs. For both people, the height of the stairs is the same. Since the heavier person has more weight, they did more work.
