A 94 cm is pulled aside a small distance and released. After 120 oscillations the amplitude is one-half of its starting value. The damping is proportional to the speed of the pendulum bob.

(a) What is the value of the damping coefficient ? if the behavior is described by the equation y(t) = yo e-?t cos(2?ft)?
