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 tension exceeds 16N. The maximum kinetic energy the object can have is: 2. Relevant equations KE=1/2mv^2 U=mgh 3. The attempt at a solution Because the object is spinning in a horizontal circle, you may take the tension at any point. Potential can equal kinetic, mgh=1/2mv^2, but I cant figure out how to start this problem.
