Question

Молот массой 100 кг падает с высоты 5 м. Какая работа была совершена?

Answer 1

Работа равна произведению силы на высоту(в нашем случае h=s) A=Fs; Нам не известна сила,найдём её F=mg,F=100кг•10H/кг=1000Н; A=1000H•5м=5000Дж=5 кДж

Answer 2

Падение молота-это механическая работа , совершаемая самим телом 

Answer 3

Calculation of Work Done by the Falling Hammer

To calculate the work done by the falling hammer, we can use the formula:

Work = Force × Distance

In this case, the force acting on the hammer is equal to its weight, which can be calculated using the formula:

Weight = Mass × Acceleration due to Gravity

Given that the mass of the hammer is 100 kg, we can calculate its weight as follows:

Weight = 100 kg × 9.8 m/s^2 Now, we need to calculate the distance the hammer falls. The height from which the hammer falls is given as 5 meters.

Therefore, the work done by the falling hammer can be calculated as:

Work = Weight × Distance

Substituting the values we have:

Work = (100 kg × 9.8 m/s^2) × 5 m

Now, let's calculate the work:

Work = 4900 J

Therefore, the work done by the falling hammer is 4900 Joules.
