Question

Турист при равномерной ходьбе в течение 3ех часов делает 15000 шагов и за каждый шаг совершает 30 Дж работы. Определить мощность туриста.

Answer 1

Дано:                   решение: 
  t=10800c              N=An/t
A=30Дж                N=15000*30/10800=41.6 Ватт
n=15000                 Ответ:41.6ватт
N-?

Answer 2

Calculation of Power

To determine the power of the tourist, we need to calculate the total work done by the tourist and divide it by the time taken. The work done can be calculated by multiplying the number of steps taken by the work done per step.

Given: - Time taken: 3 hours - Number of steps: 15,000 - Work done per step: 30 J

To calculate the total work done, we multiply the number of steps by the work done per step: Total work done = Number of steps * Work done per step

Total work done = 15,000 * 30 J

Now, we can calculate the power using the formula: Power = Total work done / Time taken

Power = (15,000 * 30 J) / 3 hours

Let's calculate the power:

Power = 450,000 J / 3 hours

To convert hours to seconds, we multiply by 3600 (60 seconds * 60 minutes): Power = 450,000 J / (3 hours * 3600 seconds/hour)

Power = 450,000 J / 10,800 seconds

Power ≈ 41.67 J/s (rounded to two decimal places)

Therefore, the power of the tourist is approximately 41.67 J/s.

Conclusion

The power of the tourist, when walking uniformly for 3 hours and taking 15,000 steps, with each step involving 30 J of work, is approximately 41.67 J/s.
