A 13.0 kg bucket of water of is suspendedby a rope wrapped around a pulley, which is just a solid cylinder0.300 m in diameter with mass 17.0 kg. The cylinder is pivoted on a frictionlessaxle through its center. The bucket is released from rest at thetop of a well and falls 12.0 m to thewater. Neglect the weight of the rope. (a) What is the tension in the rope while the bucket isfalling? N (b) With what speed does the bucket strike the water? m/s (c) What is the time of fall? s (d) While the bucket is falling, what is the force exerted on thecylinder by the axle? N
