What is the power of a person when walking if he takes 10,000 steps in 2 hours and completes 40J of work for each step?

These tasks: t (duration of a person’s walking) = 2 h (120 min = 7200 s); n (number of steps taken by a person) = 10,000 steps; A1 (work done by a person in one step) = 40 J.

Let’s define the formula for calculating the power of a person when walking: N = A / t = n * A1 / t.

Let’s make the calculation: N = 10000 * 40/7200 = 55.56 W.

Answer: A person develops a power of 55.56 watts when walking.
