Leaky cement bucket A 350 kg-bucket containing 4650 kg of cement is resting on the ground when a crane begins lifting it at a constant rate of 5 m/min. As the crane raises the bucket, cement leaks out of the bucket at a constant rate of 100 kg/min. How much work is required to lift the bucket a distance of 30 m if we ignore the weight of the crane cable attached to the bucket?
