~Radius equals length of the cord times the sin theta, where theta is the angle formed by the cord and the center of the circle. ~Velocity equals 2 pi times the radius over the Time it takes to complete one rotation. ~Time equals 2 pi times the sqaure root of length times cos theta divided by gravity.
