A 2.23 kg disc is attached to the end of a string whose length is0.540 m. The disc slides without friction on a horizontal surfaceas indicated in the Figure. If the string can withstand a maximumtension of 89.7 N, what is the maximum tangential speed the disccan have before the cord breaks?
The disc is whirled in a vertical circle of the same radius about afixed point. Find the tension at the top if the speed at the top is3.46 m/s.
