Answer:

100,000 times

Jenny climbs a set of stairs and does 2,400 J of work in 6 seconds. What is her power output?
Hatshy [7]
Power is Work/Time. Now that we have this formula, we can work this problem out.
Our work is 2,400J, and our time is 6s.
Divide 2400J by 6s.
2400/6 = 400.
Our power is 400W (watts).
I hope this helps!
