A bucket of mass 2.00 kilogram is whirled in a vertical circle of radius 1.10 meter. At the lowest point of its motion the tension in the rope supporting the bucket is 25.0 Newton.
(a) Determine what the speed of the bucket.
(b) Determine how fast must the bucket move at the top of the circle so that the rope does not go slack?
