Consider a particle with mass \(m\) moving in a potential \(U=k x^{2} / 2,\) as in a mass-spring system. The total energy of the particle is \(E=p^{2} / 2 m+k x^{2} / 2\). Assume that \(p\) and \(x\) are approximately related by the Heisenberg uncertainty principle, so \(p x \approx h .\) (a) Calculate the minimum possible value of the energy \(E,\) and the value of \(x\) that gives this minimum \(E\).
