A mass M of 2.95 kg is attached to the end of a string whose length is 0.420 m. The mass slides without friction on a horizontal surface as indicated in the diagram.
If the string can withstand a maximum tension of 127.5 N, what is the maximum tangential speed the ball can have before the cord breaks?
The mass, with a new string, is whirled in a vertical circle of the same radius about a fixed point. Find the magnitude of the tension when the mass is at the top if its speed at the top is 7.11 m/s.
