6. A ball free to move in two dimensions is subject to the spring force F=-kr spring has natural length r = 0. We assume the Hint: Determine the total energy in polar coordinates. This almost yields a “nice" Differential Equation, except for the theta term. Use angular momentum conservation to substitute for theta to resolve that problem. Now determine r(t) and then t(t).
