1. The problem statement, all variables and given/known data An object is constrained by a cord to move in a circular path of radius 0.5m on a horizontal frictionless surface. The cord will break if its tension exceeds 16 N. What is the maximum kinetic energy? 2. Relevant equations T=mg KE=1/2mv2 3. The attempt at a solution Really lost on this problem. Am I applying the wrong formulas?
