Mass attached to a spring is released: Frequency and amplitude of SHM

Not what you're looking for?

82. A massless spring with spring constant 19 N/m hangs vertically. A body of mass 0.20 kg is attached to its free end and then released. Assume that the spring was unstretched before the body was released.

Find
(a) how far below the initial position the body descends, and the
(b) frequency and
(c) amplitude of the resulting SHM.

Solution Summary

The frequency and amplitude of the mass attached to a spring is determined. How far below the initial position the body descends is determined.
