Question

Лошадь равномерно тянет воз со скоростью 0/6м / с, прикладывая усилия 300Н.Какая работа выполняется при этом за 0.5 ч?

Answer 1

A=F*S
S=V*t
A=F*V*t=300*0.6*1800=324000 (Дж)=324 (кДж)

Answer 2

Calculation of Work Done by a Horse

To calculate the work done by a horse pulling a cart, we can use the formula:

Work = Force × Distance

In this case, the force applied by the horse is 300 N, and the distance covered is 0.6 m. We need to convert the time from hours to seconds, as the formula requires the time to be in seconds.

Given that the time is 0.5 hours, we can convert it to seconds by multiplying it by 3600 (since there are 3600 seconds in an hour):

0.5 hours × 3600 seconds/hour = 1800 seconds

Now, we can calculate the work done:

Work = Force × Distance = 300 N × 0.6 m = 180 J

Therefore, the work done by the horse in 0.5 hours is 180 Joules (J) [[1]].
