A 15.0kg bucket of water is suspended by a rope of negligible weight that is wrapped around a solid cylinder 0.300m in diameter and with mass 12.0kg . The cylinder pivots on a frictionless axle through its center. The bucket is released from rest at the top of a well and falls 10.0m to the water.
What is the tension in the rope while the bucket is falling?
What is the time of fall?
While the bucket is falling, what is the force exerted on the cylinder by the axle?
