O Sketch the evolution of (§(7), 5(7)) in phase space when y = 0? How is the distance from the origin realted to the energy of the oscillator?What does this

imply for the admissible initial positions of the trajectory in phase space? The time derivative of Ɛ is strictly negative when y > 0. What does this imply for the evolution of the trajectory in phase space? Where will it end for large times 7> 1?
