A 86.0 cm pendulum is released from a small angle. After 107 oscillations the amplitude is one half of it's original value. The damping is proportional to the speed of the pendulum bob. Find the value of the damping coefficient [tex] \alpha [/tex], in Hz. I think the period is .009 s, using 1/107, but I'm not sure if that is even right. I don't really have any idea what to do. Can someone please help?
