Question

Лощадь со скоростью 2м/с равномерно перемещает телегу.Какую работу совершает лощадь за 2 часа.,если сила тяги составляет 500Н?​

Answer 1

Дано:

υ=2 м/с

t=2ч=7200 с

F=500 Н

A-?

A=Fs, где s=υt=2×7200=14400 м

A=500×14400=7200000 Дж

Ответ:A=7200000 Дж.

Answer 2

Horse's Work Done in Moving a Cart

A horse is moving a cart at a constant speed of 2 m/s, exerting a force of 500N. We need to calculate the work done by the horse in 2 hours.

Work Done Formula: The work done by a force is given by the formula: Work = Force × Distance

Calculating Work Done

Given: - Force (F) = 500N - Speed (v) = 2 m/s - Time (t) = 2 hours

First, let's calculate the distance traveled by the horse using the formula: Distance = Speed × Time

Distance = 2 m/s × 2 hours Distance = 2 m/s × 7200 s (since 1 hour = 3600 seconds) Distance = 14400 meters

Now, we can calculate the work done by the horse using the formula: Work = Force × Distance

Work = 500N × 14400m Work = 7200000 joules

So, the horse does 7200000 joules of work in moving the cart for 2 hours at a speed of 2 m/s with a force of 500N.
