The amplitude of a simple pendulum is measured as a function of time with a detector. The obtained data are shown in the table below.
From this data, plot the graph of 
as a function of time 
.
Read from the graph the type of oscillation of the pendulum.
Calculate the angular frequency of the oscillation and the damping coefficient.
What is the length of the pendulum?
and the damping coefficient is equal to 
.
.
