4 An oscillating mass is attached to an ideal spring. The mass sits on a horizontal table and all forces other than the spring force cancel out. A. The period of the oscillation depends on the mass, the spring constant, and the oscillation amplitude. B. The period of the oscillation depends on the mass, the spring constant, and the initial displacement. C. The period of the oscillation depends on the mass and the spring constant. D. The period of the oscillation depends on the mass, the spring constant, the initial displacement, and the initial velocity.
