A 15.0 kg k g bucket of water is suspended by a very light rope wrapped around a solid uniform cylinder 0.300 m m in diameter with mass 11.0 kg k g . The cylinder pivots on a frictionless axle through its center. The bucket is released from rest at the top of a well and falls 10.5 m m to the water.
(a) What is the tension in the rope while the bucket is falling?
(b) With what speed does the bucket strike the water?
(c) What is the time of fall?
(d) While the bucket is falling, what is the force exerted on the cylinder by the axle?
