## Homework Statement

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:

## Homework Equations

KE=1/2mv^2

U=mgh

## 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 can't figure out how to start this problem.
