 Homework Statement:

 Relevant Equations:

w=sqrt((k/m)(b/(2m))^2)
Amplitude = (Amax)e^((b/(2m)t)
So first I tried to find b.
0.454=(0.6)e^((b/(2*11.6)*50)
Anyways with some natural log algebra etc. I get b = 0.129378
But when I plug this into the same equation only changing mass to 17.7 kg I get 0.4998 or 50% when the answer should be 59.6%?
