Homework Statement
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 .
Homework Equations
f (x) = -bv (x)
curly:} w'=sqrt(k/m - b^2/4m^2)
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, what's the best way to calculate angular frequency (curly:} w')?
