Question

How much power is needed to get up the stairs, if I can do this with 30 Joules of work in 3 seconds?

Answer 1

10 Joules/second

Explanation:

To find the power needed to get up the stairs, we need to divide the amount of work done (30 Joules) by the time it took to do the work (3 seconds):

Power = Work / Time

Power = 30 Joules / 3 seconds

Power = 10 Joules/second

Therefore, it takes 10 Joules/second of power to get up the stairs.
