Question

Какова мощность человека при ходьбе, если за 1ч 41м ч он делает 10000 шагов и за каждый шаг совершает 40Дж работы?​

Answer 1

Ответ:

1 ч 41 минута = 6060 секунд

6060×40Дж:10000 = 24,24Вт

Answer 2

Ответ:

Мощность человека ≈ 66 Вт

Объяснение:

t = 1 ч 41 мин = 101 мин = 6060 с

n = 10 000 шагов

А₁ = 40 Дж

-----------------------

N - ?

------------------------

Работа, совершаемая человеком, проходящим n шагов

А = А₁ · n = 40 · 10 000 =  400 000 (Дж)

Мощность человека

N = A : t = 400 000 : 6060 ≈ 66 (Вт)

Answer 3

Calculation of Power during Walking

To calculate the power exerted by a person during walking, we need to know the work done per step and the number of steps taken in a given time period.

Given: - Distance covered in 1 hour and 41 minutes (1h 41m) = 41 meters - Number of steps taken = 10,000 - Work done per step = 40 Joules

To find the power, we can use the formula:

Power = Work / Time

In this case, the work done is the total work done in 10,000 steps, and the time is 1 hour and 41 minutes converted to seconds.

Calculation Steps:

1. Convert 1 hour and 41 minutes to seconds: - 1 hour = 60 minutes = 60 * 60 seconds = 3600 seconds - 41 minutes = 41 * 60 seconds = 2460 seconds - Total time = 3600 + 2460 = 6060 seconds

2. Calculate the total work done: - Total work = Work per step * Number of steps = 40 J/step * 10,000 steps = 400,000 J

3. Calculate the power: - Power = Total work / Time = 400,000 J / 6060 s ≈ 65.97 Watts

Therefore, the power exerted by the person during walking is approximately 65.97 Watts.

Please note that this calculation assumes a constant walking speed and a uniform distribution of work done over the entire duration of walking. Additionally, individual variations in walking efficiency and energy expenditure may affect the actual power output.
