(6%) Problem 3: A farmer is using a rope and pulley to lift a bucket of water from the bottom of a well that is hy = 12 m deep. The farmer uses a force F = 56.5 N to pull the bucket of water directly upwards. The total mass of the bucket of water is my + mw = 4.2 kg. 25% Part (a) Select the correct free body diagram. mg m.g ✔ Correct! 25% Part (b) Calculate how much work Wein J the farmer does on the bucket of water (via the rope) to raise it to ground level.
