Question

2)Лошадь равномерно везет телегу со скоростью 0,5м/с, прилагая усилие 100Н. Какая работа совершается при этом за 3 часа?​

Answer 1

Ответ:

540000Дж

Объяснение:

v=0,5м/с F=100н t=3ч=3600*3=10800с.

A=?

A=F*S S=v*t A=F*v*t

A=100н*0,5м/с*10800с=540000Дж

Answer 2

Ответ:

540000Дж или 540КДж

Объяснение:

А-работа

F-сила

t-время

v-скорость

S-расстояние

3ч=10800с

S=v*t

А=F*S=F*v*t=100Н*0,5м/с*10800с=540000Дж=540КДж

Answer 3

Calculation of Work

To calculate the work done, we can use the formula:

Work = Force × Distance

In this case, the force applied by the horse is 100 N, and the distance traveled is the product of the speed and time.

Given: - Speed of the horse: 0.5 m/s - Time: 3 hours

To calculate the distance traveled, we need to convert the time from hours to seconds:

Time in seconds = 3 hours × 60 minutes/hour × 60 seconds/minute

Let's calculate the time in seconds:

3 hours × 60 minutes/hour × 60 seconds/minute = 10,800 seconds

Now, we can calculate the distance traveled:

Distance = Speed × Time

Distance = 0.5 m/s × 10,800 seconds

Let's calculate the distance:

Distance = 5,400 meters

Now, we can calculate the work done:

Work = Force × Distance

Work = 100 N × 5,400 meters

Let's calculate the work:

Work = 540,000 joules

Therefore, the work done by the horse in 3 hours is 540,000 joules.
