Homework Help: Physics Circular Motion

Posted by Mike Joseph on Saturday, June 16, 2012 at 5:13pm.

A 0.40-kg ball, attached to the end of a horizontal cord, is rotated in a circle of radius 2.0 m on a frictionless horizontal surface.

If the cord will break when the tension in it exceeds 75 N, what is the maximum speed the ball can have?

May someone please walk me through this problem step by step
