Homework Statement
In a science museum, a 110 kg brass pendulum bob swings at the end of a 15.0-m-long wire. The pendulum is started at exactly 8:00 a.m. every morning by pulling it 1.5 m to the side and releasing it. Because of its compact shape and smooth surface, the pendulum's damping constant is only 0.010 kg/s.
a. At exactly 12:00 noon, how many oscillations will the pendulum have completed?
b. And what is its amplitude?
Homework Equations
w=sqrt(k/m-b^2/4m^2)
tau=m/b
w=sqrt(g/L)
The Attempt at a Solution
i've got nothing this makes no sense to me, if someone could just give me a hint on where to start...
