Question

We did a lab where we climbed stairs and we were timed. The stairs were 2.373 meters tall and I climbed them in 2.91seconds. I got 1427.88 joules (w=mgy) and 490.68 watts (p=w/t).
Our lab is asking us this: "Your local electric company supplies you 1 kw of power for 1hour for 8 cents. Assume that you could climb stairs continuouslyfor 1 hour. How much money would this climb be worth?"
This is where our class begins to disagree. I tried simply.49068kW *8 = cost in cents (about 3.925 cents). Myclassmates seem to disagree. How do I do this because I don't trustthe way I did it. I have a feeling a 3600 is involved somewhere inthe equation. The stairs were 2.373 meters tall and I climbed them in 2.91seconds. I got 1427.88 joules (w=mgy) and 490.68 watts (p=w/t).
