Springs and Harmonics Practice Test

What is the period for a block attached to a spring with a spring constant of after it is compressed by and released?

A mass hanging in equilibrium is attached to a fixed surface on the ceiling by a spring. The mass is pulled down from the ceiling, then released and allowed to move in simple harmonic motion. The mass does not lose energy due to friction or air resistance. Which of the following would increase the frequency with which the mass moves through the equilibrium position?
