(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A hard-boiled egg of mass 51.0kg moves on the end of a spring with force constant 25.7N/m. Its initial displacement is 0.293m. A damping force f (x) = -bv (x) acts on the egg, and the amplitude of the motion decreases to 0.101m in a time of 4.55s.

Calculate the magnitude of the damping constant .

2. Relevant equations

f (x) = -bv (x)

curly:} w'=sqrt(k/m - b^2/4m^2)

3. The attempt at a solution

I used:

f (x) = -bv (x)

rearranged to give:

b = -f/v (x)

but this didn't work

Do I have to use:

curly:} w'=sqrt(k/m - b^2/4m^2)

and if so, whats the best way to calculate angular frequency (curly:} w')?
