Working with centripetal motion - mass attached to string

Hi. Can someone show me how to do the the following problem?
"A mass M of 2.71 kg is attached to the end of a string whose length is 0.640 m, and is whirled in a vertical circle in 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 5.73 m/s."
(I don't think you need this information, but just in case. . . This is part II of a two-part question. In part I, we're told that the string can withstand a maximum tension of 77.1 N and that the maximum tangential speed the ball can have before the string breaks is 4.27 m/s.)

This is an example of uniform circular motion. In the case of uniform circular motion, the velocity is not constant(as the direction is continuously changing) but the SPEED remains ...
Step by step solution with good explanations. A figure is given for clarity of explanations.
