Physics HW Help?
A farmer is using a rope and pulley to lift a bucket of water from the bottom of a well that is hy = 15 m deep. The farmer uses a force F1 = 51.5 N to pull the bucket of water directly upwards. The total mass of the bucket of water is mb + mw = 3.9 kg.
A.) Calculate how much work Wf in J the farmer does on the bucket of water (via the rope) to raise it to ground level.
B.) Calculate how much work Wg in J gravity does on the bucket filled with water as the farmer lifts it up the well.
C.) Calculate the net work Wnet in J done on the bucket of water by the two forces F1 and Fg.
