Homework Statement
A bucket of mass 2.00kg is whirled in a vertical circle of radius 1.10 m. At the lowest point of its motion the tension in the rope supporting the bucket is 25.0 N. a) Find the speed of the bucket. b) How fast must the bucket move at the top of the circle so that the rope does not go slack?

The Attempt at a Solution
I have solved for the net force in the Y direction and I get 5.4N. Is this the net centripetal force that i can use to plug back into F=m *ac for the centripetal acceleration? I get 2.7m/s when i do this. I know this question has been posted before, and I'm sorry but I don't quite get it after reading and rereading bits and pieces of information by others posted in the forum. all help is greatly appreciated!
