A person lifts a bucket of water weighing 10 kg from a well 8 m deep in 16 seconds.

A person lifts a bucket of water weighing 10 kg from a well 8 m deep in 16 seconds. What power does it develop at the same time?

Initial data: t (bucket lifting time) = 16 s; h (well depth) = 8 m; m (mass of a bucket with water) = 10 kg.

Reference values: g (acceleration due to gravity) = 10 m / s2.

The power that a person will develop when lifting a bucket can be calculated by the formula: N = A / t = F * h / t = m * g * h / t.

Let’s calculate: N = 10 * 10 * 8/16 = 50 W.

Answer: When lifting a bucket of water from a well, a person will develop a power of 50 watts.
