Question

Какую сред. Мощь развивает человек поднимающий ведро весом 500Н из колодца глуб. 10м за 60с.?

Answer 1

S=10 м
t=60 с
P=A/t=FS/t=500*10/60=500/6=250/3≈83 Ватт

Answer 2

Calculating the Power Output

To calculate the power output of a person lifting a bucket from a well, we can use the formula:

Power (P) = Work (W) / Time (t)

Where: - Work (W) is the force applied multiplied by the distance over which the force is applied. - Time (t) is the duration over which the work is done.

Given: - Force (F) = 500 N (Newtons) - Distance (d) = 10 m (meters) - Time (t) = 60 s (seconds)

Calculating Work

First, let's calculate the work done in lifting the bucket out of the well. The work done is given by the formula:

Work (W) = Force (F) × Distance (d)

Substitute the given values: W = 500 N × 10 m = 5000 J (Joules)

Calculating Power

Now, we can calculate the power using the work and time values: Power (P) = 5000 J / 60 s = 83.33 W (Watts)

So, the person is exerting a power of approximately 83.33 Watts while lifting the bucket from the well.
