Afarmer is using a rope and pulley to lift a bucket of water from the bottom of a well. the farmer uses a force f1=57.5 n to pull the bucket of water upwards. the total mass of the bucket of water is f2= 3.9kg.
-calculate how much work wg in j gravity does on the bucket filled with water as the farmer lifts it up the well.
-calculate the net work wnet in j done on the bucket of water by the two forces f1 and fg.
