Question

A spring has a force constant of B0 N/m, it vibrates with a frequency of 7 Hz. Calculate the,

a) period;

b) angular frequency:

c) mass of the spring,

Answer 1

Answer

a) period

$T=\frac{1}{T}=\frac{1}{7}=0.14$ sec

b) angular frequency

$w=\frac{2\pi}{T}=48.8rad$ /sec

c)

mass of the spring,

$m=\frac{k}{w^2}=0.04kg$
