[QUOTE="haruspex, post: 4939952, member: 334404"] Yes. You are not told it is the minimum speed to maintain circular motion, so you've no basis for saying the tension is 0 there. Yes. No, it won't be constant velocity. Start again, but taking the tension at the top to be some unknown value. Derive everything else in terms of that, including the time to complete a swing (that's the hard bit). Then set that time equal to 1. [/QUOTE]
