Abucket of mass 2.00 kg is whirled in a vertical circle of radius 1.20 m . at the lowest point of its motion the tension in the rope supporting the bucket is 27.0 n.
a) find the speed of the bucket (hint: draw a free-body diagram of the bucket at the bottom of the motion.
b) how fast must the bucket move at the top of the circle so that the rope does not go slack? (hint: draw a free-body diagram of the bucket at the top of the motion.)
