A bucket weighing 10 kg was raised from a well 5 m deep. Calculate the work done.

m = 10 kilograms – the mass of the bucket;

g = 10 Newton / kilogram – acceleration of gravity;

h = 5 meters – the depth of the well from which the bucket was raised.

It is required to determine A (Joule) – the work done to lift the bucket.

Since it was not specified in the problem statement, we assume that the bucket was raised evenly. Then, the force with which it is necessary to lift the bucket will be equal to the force of gravity:

F = F gravity = m * g = 10 * 10 = 100 Newtons.

The perfect work will be equal to:

A = F * h = 100 * 5 = 500 Joules.

Answer: Work is 500 Joules.
