Part A:

A mass of 210 g oscillates on a horizontal frictionless surface at a frequency of 2.2 Hz and with amplitude of 5.0 cm.

Find the effective spring constant for this motion.

Thus, the motion is simple harmonic motion.

Here  Hz and .

For horizontal frictionless surface:

Frequency of object in simple harmonic motion is  .

Substitute corresponding values in .

N/m.

Effective spring constant for this motion is 40.12 N/m.
