A block attached to an ideal spring oscillates on a frictionless horizontal surface (simple harmonic motion). At what point(s) in the motion is the block’s kinetic energy maximized and at what point(s) is the spring potential energy maximized? Explain how energy is exchanged between kinetic and potential forms during one cycle. Be sure to record your answers and justification on your paper and submit it to Gradescope at the end of the exam. (10 points)
