1) A 15.0 kg bucket of water is suspended by a very light rope wrapped around a solid uniform cylinder 0.300 m in diameter with a mass of 12.0 kg. The cylinder pivots on a frictionless axle through its center. The bucket is released from rest at the top of the well. What is the tension in the rope while the bucket is falling?
2) For the bucket described in the previous problem, what is its speed after falling a distance of 10.0 m?
