A bucket of water weighing 10 kg was raised from a well 5 meters deep. Calculate the perfect work?

As we know from the school curriculum in physics, the work that was done when lifting any load in general form can be calculated using the following formula:

A = F * h = m * g * h, where m is the mass of the load being lifted.

Let’s determine what value the work will be equal to, what was done while lifting a bucket of water weighing 10 kilograms, if from the condition of our problem we know for sure that the depth of the well is 5 meters:

10 * 10 * 5 = 500.

Answer: Perfect work is 500 J (D).
