Describe why it is necessary that the conically shaped spring is hung with the smaller end at the top. Why is a cylindrically shaped spring not being used in this experiment?

2. During simple harmonic oscillation, is the acceleration of a simple harmonic oscillator equal to zero at some point? If so, where in the oscillation would this be located?

3. A mass, attached to the bottom of a vertically hung spring, stretches the spring by 30 centimeters to a new static equilibrium position. When set into oscillation what is the period of oscillation? (Let m_c = 0)

4.For a simple harmonic oscillator the kinetic energy is equal to mv², and the potential energy is equal to kx². When the displacement is equal to one-half the amplitude of oscillation, what fraction of the total energy is kinetic and what fraction of the total energy is potential?
