A person lifts a bucket of water weighing 12 kilograms from a well 10 meters deep in 15 seconds. find the power.
These tasks: t (duration of lifting the bucket with water) = 15 s; h (lifting height) = 10 m; m (bucket weight) = 12 kg.
Constants: g (acceleration due to gravity) ≈ 10 m / s2.
The power that a person has developed when lifting a bucket from a well is calculated by the formula: N = A / t = m * g * h / t.
Calculation: N = 12 * 10 * 10/15 = 80 W.
Answer: A man, when lifting a bucket, developed a power of 80 watts.
One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society.
