Question

A mass attached to a horizontal spring undergoes simple harmonic motion. Which of the following are correct? (Select all that apply.) Ignore any type of friction.

If one cuts the spring at the moment when the mass is at its maximum displacement from the equilibrium position, the mass will remain at rest.

Instantaneous kinetic energy of the mass is maximum when instantaneous potential energy of the spring is minimum.

The period of small oscillations of the mass depends on the amplitude.

The horizontal speed of the mass is zero when the magnitude of its acceleration is maximum.

The magnitude of acceleration of the mass is maximum when the ball is at its equilibrium position.

Explanation / Answer

The correct options are

1) If one cuts the spring at the moment when the mass is at its maximum displacement from the equilibrium position, the mass will remain at rest.

2) The period of small oscillations of the mass depends on the amplitude.

3) The magnitude of acceleration of the mass is maximum when the ball is at its equilibrium position.
