Human power can be expressed by the formula:
N = A / t, where A is the complete mechanical work performed by a person (A = 600 J), t is the time of a person’s movement during ascent (t = 15 s).
Let’s calculate the power of a person:
N = A / t = A / t = 600/15 = 40 W
Answer: The power of a person when lifting is 40 watts.
One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society.
