Question

Determine the spring constant if a 2000 g mass is applied to a mass spring system causing it to isolate at a frequency of 4HZ

Answer 1

Answer:

128.8 N/m

Explanation:

Frequency for a spring attached oscillating mass is f=1/2π$\sqrt{k/m]$,

where k is the stiffness of the spring (or spring constant) and m is the mass

Solving for k

f²(4$\pi^{2}$)=k/m

k=m(f²(4$\pi^{2}$))=2000(16·4·3.14²) = 1262/9.8=128.8 N/m
