Questions #1-12: A mass m is attached to the end of an ideal, massless spring with constant k, as shown. The mass is initially displaced to the right of the spring's equilibrium position by a distance A, then released and allowed to oscillate freely. The mass then repeatedly passes through positions QRSPQ. Neglect all friction, unless told otherwise. 9. For a frictionless system like this one, which of the following quantities will have a constant value at all times? Select ALL that apply: Partial credit is NOT allowed for this question. P-> m S ER A. period B. frequency C. spring constant D. amplitude of oscillation E. total mechanical energy of system
