A man pulls a bucket out of a deep well. What work does he do in 1 minute if he moves the rope at a speed of 25 m / s? Bucket weight 10 kg.
To find the amount of work done when pulling a bucket out of a deep well, use the formula: A = N * t = Fт * V * t = m * g * V * t.
Constants and variables: m is the mass of the bucket (m = 10 kg); g – acceleration due to gravity (g ≈ 10 m / s2); V is the speed of picking the rope (V = 25 m / s); t is the duration of the bucket lifting (t = 1 min = 60 s).
Calculation: A = m * g * V * t = 10 * 10 * 25 * 60 = 150 * 10 ^ 3 J.
Answer: In 1 minute, a person must complete a work of 150 kJ.
